Cerebrospinal fluid

Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spine. It is produced in the choroid plexuses of the ventricles of the brain. It acts as a cushion or buffer for the brain's cortex, providing basic mechanical and immunological protection to the brain inside the skull. The CSF also serves a vital function in cerebral autoregulation of cerebral blood flow.

The CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It constitutes the content of the ventricles, cisterns, and sulci of the brain, as well as the central canal of the spinal cord.

There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid.

Structure

Production

The brain produces roughly 500 mL of cerebrospinal fluid per day. This fluid is constantly reabsorbed, so that only 100-160 mL is present at any one time.

Caesium fluoride

Caesium fluoride or cesium fluoride is an inorganic compound usually encountered as a hygroscopic white solid. It is used in organic synthesis as a source of the fluoride anion. Caesium has the lowest electronegativity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.

Synthesis and properties

Caesium fluoride can be prepared by the reaction of caesium hydroxide (CsOH) with hydrofluoric acid (HF). The resulting salt can then be purified by recrystallization. The reaction is shown below:

Another way to make caesium fluoride is to react caesium carbonate (Cs₂CO₃) with hydrofluoric acid. The resulting salt can then be purified by recrystallization. The reaction is shown below:

In addition, elemental fluorine and caesium can be used to form caesium fluoride as well, but doing so is very impractical because of the expense. While this is not a normal route of preparation, caesium metal reacts vigorously with all the halogens to form caesium halides. Thus, it burns with fluorine gas, F₂, to form caesium fluoride, CsF according to the following reaction:

Granulocyte macrophage colony-stimulating factor

Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, NK cells, endothelial cells and fibroblasts that functions as a cytokine. The pharmaceutical analogs of naturally occurring GM-CSF are called sargramostim and molgramostim.

Function

GM-CSF is a monomeric glycoprotein that functions as a cytokine - it is a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exit the circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells. Thus, it is part of the immune/inflammatory cascade, by which activation of a small number of macrophages can rapidly lead to an increase in their numbers, a process crucial for fighting infection.

GM-CSF also has some effects on mature cells of the immune system. These include, for example, inhibiting neutrophil migration and causing an alteration of the receptors expressed on the cells surface.

Fluid

In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids. Fluids can be defined as substances that have zero shear modulus or in simpler terms a fluid is a substance which cannot resist any shear force applied to it.

Although the term "fluid" includes both the liquid and gas phases, in common usage, "fluid" is often used as a synonym for "liquid", with no implication that gas could also be present. For example, "brake fluid" is hydraulic oil and will not perform its required incompressible function if there is gas in it. This colloquial usage of the term is also common in medicine and in nutrition ("take plenty of fluids").

Liquids form a free surface (that is, a surface not created by the container) while gases do not. The distinction between solids and fluid is not entirely obvious. The distinction is made by evaluating the viscosity of the substance. Silly Putty can be considered to behave like a solid or a fluid, depending on the time period over which it is observed. It is best described as a viscoelastic fluid. There are many examples of substances proving difficult to classify. A particularly interesting one is pitch, as demonstrated in the pitch drop experiment currently running at the University of Queensland.

Rushes (album)

Rushes is a 1998 ambient techno album by The Fireman, a duo consisting of Paul McCartney and producer Youth.

Recording

One line of lyrics included in the song "Palo Verde" was taken from an unreleased track of McCartney's, titled "Let Me Love You Always". Similarly, bits from another unreleased song, "Hey Now (What Are You Looking at Me For?)", was used in "Bison", "Auraveda" and "7 a.m.". Both unreleased tracks were recorded at some point during 1995, at McCartney's The Mill studio. In an edition of Club Sandwich magazine, two more songs were mentioned: "Plum Jam" and "Through the Marshes". All of the tracks featured on the album were recorded early 1998.

Release and reception

Better received than predecessor Strawberries Oceans Ships Forest, Rushes is distinguished by not relying so much on McCartney's previous recordings.

Rushes was released in the UK on Hydra on 21 September 1998, while in the US it was released on Capitol on 20 October 1998. The album was also released on double vinyl. Two 12" singles were released from the album, both mixes of "Fluid". The first 12", released on the same day as and with the same name as the album, contains the tracks "Fluid", "Appletree Cinnabar Amber", and an extended version of an album track titled "Bison (Long One)". The second 12" was released in 1999, as a limited edition of 3000, titled Fluid (Nitin Sawhney Remixes), and features three remixes of "Fluid" ("Fluid (Out of Body and Mind Mix)", "Fluid (Out of Body Mix)" and "Fluid (Out of Body with Sitar Mix)") and the album version of "Bison". Like the duo's first album,Rushes was a no-show on the charts and is also no longer in print.

The cerebrospinal fluid or CSF is the liquid that bathes the central nervous system (the brain and the spinal cord). The CSF ensures: - The protection of the central nervous system against mechanical shocks and vibrations. - it plays an important role in the regulation of intracranial pressure. - It participates in the cerebral metabolic processes by regulating the exchange of substances. and, provides many other functions as well. The CSF circulates in two different compartments: - The first is the inner brain ependymal cavities or ventricles, - the second is the compartment surrounding the central nervous system, it corresponds to the sub-arachnoid space. The CSF is secreted by the choroid plexus: clusters of capillary blood vessels located in the ventricular system. The ventricular system consists of four ventricles connected by many channels. It is connected to the central canal of the spinal cord. There are two lateral ventricles, occupying the center of the cerebral hemispheres. Both are connected to the third ventricle at the center of the diencephalon by the foramina of Monro. The third ventricle is connected to the fourth ventricle in the brainstem by the aqueduct of Sylvius. The CSF will leave the fourth ventricle through the foramen of Magendie to fill the sub-arachnoid space between the pia mater and the arachnoid. The CSF is then absorbed at the top of the skull by the arachnoid granulations of Pakioni.

The cerebrospinal fluid or CSF is the liquid that bathes the central nervous system (the brain and the spinal cord). The CSF ensures: - The protection of the central nervous system against mechanical shocks and vibrations. - it plays an important role in the regulation of intracranial pressure. - It participates in the cerebral metabolic processes by regulating the exchange of substances. and, provides many other functions as well. The CSF circulates in two different compartments: - The first is the inner brain ependymal cavities or ventricles, - the second is the compartment surrounding the central nervous system, it corresponds to the sub-arachnoid space. The CSF is secreted by the choroid plexus: clusters of capillary blood vessels located in the ventricular system. The ventricular system consists of four ventricles connected by many channels. It is connected to the central canal of the spinal cord. There are two lateral ventricles, occupying the center of the cerebral hemispheres.

There are four ventricles in the brain that house cerebrospinal fluid (CSF): two lateral ventricles, a third ventricle and a fourth ventricle. Watch the full length video to learn everything about the ventricles of the brain: https://khub.me/kn5qy Oh, are you struggling with learning anatomy? We created the ★ Ultimate Anatomy Study Guide ★ to help you kick some gluteus maximus in any topic. Completely free. Download yours today: https://khub.me/sf0si A ventricle is a hollow area or cavity within an organ usually filled with some kind of fluid. Our brain has four interconnected ventricles and the fluid that fills them is called cerebrospinal fluid. Cerebrospinal fluid is a clear fluid that has several important functions in our central nervous system and you might be wondering where this fluid comes from. Well, almost every part of the ventricular system that we're going to see in the full version of this tutorial contains a choroid plexus which includes epithelial cells that produce the cerebrospinal fluid. So as I just mentioned there are four ventricles within the brain – two lateral ventricles (the left and right lateral ventricles), the third ventricle found near the central of the brain, and the fourth ventricle located deep to the cerebellum. There is a lateral ventricle in each hemisphere of the brain and therefore there's a left lateral ventricle and a right lateral ventricle, each found in the respective side of the brain. Here we can see the right lateral ventricle hiding behind the left lateral ventricle as we're viewing these structures from the left hand side. On the full version of this tutorial, we will look at the following topics: - anatomy and function of the ventricles of the brain; - clinical notes related to the ventricles of the brain: hydrocephalus.

CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. There is about 125 mL of CSF at any one time, and about 500 mL is generated every day. CSF acts as a shock absorber, cushion or buffer, providing basic mechanical and immunological protection to the brain inside the skull. CSF also serves a vital function in the cerebral autoregulation of cerebral blood flow. CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It fills the ventricles of the brain, cisterns, and sulci, as well as the central canal of the spinal cord. There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid. The ependymal cells of the choroid plexus have multiple motile cilia on their apical surfaces that beat to move the CSF through the ventricles. A sample of CSF can be taken from around the spinal cord via lumbar puncture. This can be used to test the intracranial pressure, as well as indicate diseases including infections of the brain or the surrounding meninges. Although noted by Hippocrates, it was forgotten for centuries, though later was described in the 18th century by Emanuel Swedenborg. In 1914, Harvey Cushing demonstrated that CSF is secreted by the choroid plexus. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to the perks: Sign up now on our website at https://members.drnajeeblectures.com/ Follow us on Facebook:- https://www.facebook.com/DrNajeeb/ Follow us on Instagram:- https://www.instagram.com/drnajeeblectures/

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I cover the ventricles. I discuss the function of the ventricles, which involves production and distribution of cerebrospinal fluid; I also briefly explain the functions of cerebrospinal fluid. I describe the structure of the ventricles, including descriptions of the lateral, third, and fourth ventricles, as well as the means by which the ventricles are connected to one another: the interventricular foramen and cerebral aqueduct. Finally, I mention hydrocephalus, a condition that occurs when cerebrospinal fluid levels in the ventricles get too high. For an article (on my website) that explains the ventricles, click this link: https://neuroscientificallychallenged.com/posts/know-your-brain-ventricles TRANSCRIPT: Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the ventricles. The ventricles are a network of cavities that are distributed throughout the brain. They are lined with a specialized membrane called the choroid plexus, which is composed of glial cells called ependymal cells. Ependymal cells are specially designed to secrete cerebrospinal fluid, which then flows through the ventricles and around the brain. Thus the main role of the ventricles is the production and distribution of cerebrospinal fluid. Cerebrospinal fluid, or CSF as it is commonly called, is a clear colorless liquid that performs a number of important functions in the brain. Among other things, csf surrounds the brain, forming a protective layer and suspending the brain in fluid, which reduces the strain forces like gravity would have on the brain. Also, it constantly flows through and around the brain removing toxins and regulating the extracellular environment of neurons. There are 4 ventricles. There are two C-shaped lateral ventricles, one in each of the cerebral hemispheres. The lateral ventricles are connected to a third ventricle by an opening called the interventricular foramen. The third ventricle is a narrow cavity that runs along the midline of the diencephalon. It looks something like a misshapen donut, and the section that would be the hole of the donut is an area known as the interthalamic adhesion. In this section the thalamus makes up the wall of the third ventricle. The third ventricle communicates with the fourth ventricle via the cerebral aqueduct. The fourth ventricle is wedged between the cerebellum on one side and the brainstem on the other. The fourth ventricle is shaped like a tent whose peak protrudes into the cerebellum. There are three openings in the fourth ventricle that allow cerebrospinal fluid to enter the subarachnoid space, a CSF-containing cavity that surrounds the brain. Thus, CSF leaves the ventricular system via the 4th ventricle. The 4th ventricle extends to, and is continuous with, the central canal, a CSF-filled cavity that runs the length of the spinal cord. If CSF circulation is blocked as by a tumor, or is otherwise abnormally excessive, it can result in increased pressure and expansion of the ventricles. This creates a condition known as hydrocephalus, which can cause a variety of complications and be life-threatening. REFERENCE: Nolte J. The Human Brain: An Introduction to its Functional Anatomy. 6th ed. Philadelphia, PA. Elsevier; 2009.

The cerebrospinal fluid or CSF is the liquid that bathes the central nervous system (the brain and the spinal cord). The CSF ensures: - The protection of the central nervous system against mechanical shocks and vibrations. - it plays an important role in the regulation of intracranial pressure. - It participates in the cerebral metabolic processes by regulating the exchange of substances. and, provides many other functions as well. The CSF circulates in two different compartments: - The first is the inner brain ependymal cavities or ventricles, - the second is the compartment surrounding the central nervous system, it corresponds to the sub-arachnoid space. The CSF is secreted by the choroid plexus: clusters of capillary blood vessels located in the ventricular system. The ventricular system consists of four ventricles connected by many channels. It is connected to the central canal of the spinal cord. There are two lateral ventricles, occupying the center of the cerebral hemispheres. Both are connected to the third ventricle at the center of the diencephalon by the foramina of Monro. The third ventricle is connected to the fourth ventricle in the brainstem by the aqueduct of Sylvius. The CSF will leave the fourth ventricle through the foramen of Magendie to fill the sub-arachnoid space between the pia mater and the arachnoid. The CSF is then absorbed at the top of the skull by the arachnoid granulations of Pakioni.

There are four ventricles in the brain that house cerebrospinal fluid (CSF): two lateral ventricles, a third ventricle and a fourth ventricle. Watch the full length video to learn everything about the ventricles of the brain: https://khub.me/kn5qy Oh, are you struggling with learning anatomy? We created the ★ Ultimate Anatomy Study Guide ★ to help you kick some gluteus maximus in any topic. Completely free. Download yours today: https://khub.me/sf0si A ventricle is a hollow area or cavity within an organ usually filled with some kind of fluid. Our brain has four interconnected ventricles and the fluid that fills them is called cerebrospinal fluid. Cerebrospinal fluid is a clear fluid that has several important functions in our central nervous system and you might be wondering where this fluid comes from. Well, almost every part of the ventricular system that we're going to see in the full version of this tutorial contains a choroid plexus which includes epithelial cells that produce the cerebrospinal fluid. So as I just mentioned there are four ventricles within the brain – two lateral ventricles (the left and right lateral ventricles), the third ventricle found near the central of the brain, and the fourth ventricle located deep to the cerebellum. There is a lateral ventricle in each hemisphere of the brain and therefore there's a left lateral ventricle and a right lateral ventricle, each found in the respective side of the brain. Here we can see the right lateral ventricle hiding behind the left lateral ventricle as we're viewing these structures from the left hand side. On the full version of this tutorial, we will look at the following topics: - anatomy and function of the ventricles of the brain; - clinical notes related to the ventricles of the brain: hydrocephalus.

CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. There is about 125 mL of CSF at any one time, and about 500 mL is generated every day. CSF acts as a shock absorber, cushion or buffer, providing basic mechanical and immunological protection to the brain inside the skull. CSF also serves a vital function in the cerebral autoregulation of cerebral blood flow. CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It fills the ventricles of the brain, cisterns, and sulci, as well as the central canal of the spinal cord. There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid. The ependymal cells of the choroid plexus have multiple motile cilia on their apical surfaces that beat to move the CSF through the ventricles. A sample of CSF can be taken from around the spinal cord via lumbar puncture. This can be used to test the intracranial pressure, as well as indicate diseases including infections of the brain or the surrounding meninges. Although noted by Hippocrates, it was forgotten for centuries, though later was described in the 18th century by Emanuel Swedenborg. In 1914, Harvey Cushing demonstrated that CSF is secreted by the choroid plexus. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to the perks: Sign up now on our website at https://members.drnajeeblectures.com/ Follow us on Facebook:- https://www.facebook.com/DrNajeeb/ Follow us on Instagram:- https://www.instagram.com/drnajeeblectures/

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I cover the ventricles. I discuss the function of the ventricles, which involves production and distribution of cerebrospinal fluid; I also briefly explain the functions of cerebrospinal fluid. I describe the structure of the ventricles, including descriptions of the lateral, third, and fourth ventricles, as well as the means by which the ventricles are connected to one another: the interventricular foramen and cerebral aqueduct. Finally, I mention hydrocephalus, a condition that occurs when cerebrospinal fluid levels in the ventricles get too high. For an article (on my website) that explains the ventricles, click this link: https://neuroscientificallychallenged.com/posts/know-your-brain-ventricles TRANSCRIPT: Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the ventricles. The ventricles are a network of cavities that are distributed throughout the brain. They are lined with a specialized membrane called the choroid plexus, which is composed of glial cells called ependymal cells. Ependymal cells are specially designed to secrete cerebrospinal fluid, which then flows through the ventricles and around the brain. Thus the main role of the ventricles is the production and distribution of cerebrospinal fluid. Cerebrospinal fluid, or CSF as it is commonly called, is a clear colorless liquid that performs a number of important functions in the brain. Among other things, csf surrounds the brain, forming a protective layer and suspending the brain in fluid, which reduces the strain forces like gravity would have on the brain. Also, it constantly flows through and around the brain removing toxins and regulating the extracellular environment of neurons. There are 4 ventricles. There are two C-shaped lateral ventricles, one in each of the cerebral hemispheres. The lateral ventricles are connected to a third ventricle by an opening called the interventricular foramen. The third ventricle is a narrow cavity that runs along the midline of the diencephalon. It looks something like a misshapen donut, and the section that would be the hole of the donut is an area known as the interthalamic adhesion. In this section the thalamus makes up the wall of the third ventricle. The third ventricle communicates with the fourth ventricle via the cerebral aqueduct. The fourth ventricle is wedged between the cerebellum on one side and the brainstem on the other. The fourth ventricle is shaped like a tent whose peak protrudes into the cerebellum. There are three openings in the fourth ventricle that allow cerebrospinal fluid to enter the subarachnoid space, a CSF-containing cavity that surrounds the brain. Thus, CSF leaves the ventricular system via the 4th ventricle. The 4th ventricle extends to, and is continuous with, the central canal, a CSF-filled cavity that runs the length of the spinal cord. If CSF circulation is blocked as by a tumor, or is otherwise abnormally excessive, it can result in increased pressure and expansion of the ventricles. This creates a condition known as hydrocephalus, which can cause a variety of complications and be life-threatening. REFERENCE: Nolte J.

Cerebrospinal fluid

Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spine. It is produced in the choroid plexuses of the ventricles of the brain. It acts as a cushion or buffer for the brain's cortex, providing basic mechanical and immunological protection to the brain inside the skull. The CSF also serves a vital function in cerebral autoregulation of cerebral blood flow.

The CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It constitutes the content of the ventricles, cisterns, and sulci of the brain, as well as the central canal of the spinal cord.

There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid.

Structure

Production

The brain produces roughly 500 mL of cerebrospinal fluid per day. This fluid is constantly reabsorbed, so that only 100-160 mL is present at any one time.
