Receptors: Types & Functions
Find notes here: https://www.nonstopneuron.com/post/receptors-types-and-functions
Explore our entire animation video library at: https://www.nonstopneuron.com/
Video Summary:
Receptors receive signals from cells exterior. They have a ligand-binding domain to recognize specific ligand and an effector domain to produce the downstream effect. Receptors for hydrophilic signal molecules are located on the cell membrane and receptors for hydrophobic molecules are located inside the cell. Various types of receptors are ligand-gated ion channels that regulate the opening or closing of the channel. G protein-coupled receptors act through G proteins and ultimately regulate the function of a wide range of enzymes and ion channels. Catalytic receptors mostly activate or inactivate a protein by phosph...

Common cell signaling pathway
What are common cell signaling pathways? To make a multicellular organism, cells must be able to communicate with one another, and to do it cells often send out tiny chemical signals that act on the receptors on other cells. Signals can be classified according to the distance between the signaling cell and the target cell. Find our full video library only on Osmosis: http://osms.it/more.
Join millions of current and future clinicians who learn by Osmosis, along with hundreds of universities around the world who partner with Osmosis from Elseiver to make medical and health education more engaging and efficient.

Inositol Triphosphate (IP3) and Calcium Signaling Pathway | Second Messenger System
Lesson on the Inositol Trisphosphate (IP3) and Calcium Signaling Pathway. IP3, calcium and diacylglycerol (DAG) are important second messengers that are unregulated upon activation of a G protein-coupled receptor. Inositol triphosphate and DAG are cleavage products of phosphatidyl inositol 4,5 bisphosphate (PIP2), which is cleaved by phospholipase C. Increasing levels of IP3 lead to augmented cytosolic calcium levels that further lead to activation of downstream cellular targets.
Hey everyone. In this lesson you will be introduced to the IP3 and calcium signaling pathway. We will also discuss the purpose of the pathway, enzymes involved in the pathway, and how the pathway is regulated.
I hope you find this video helpful. If you do, please like and subscribe for more videos like this one....

Lesson on the Inositol Trisphosphate (IP3) and Calcium Signaling Pathway. IP3, calcium and diacylglycerol (DAG) are important second messengers that are unregulated upon activation of a G protein-coupled receptor. Inositol triphosphate and DAG are cleavage products of phosphatidyl inositol 4,5 bisphosphate (PIP2), which is cleaved by phospholipase C. Increasing levels of IP3 lead to augmented cytosolic calcium levels that further lead to activation of downstream cellular targets.
Hey everyone. In this lesson you will be introduced to the IP3 and calcium signaling pathway. We will also discuss the purpose of the pathway, enzymes involved in the pathway, and how the pathway is regulated.
I hope you find this video helpful. If you do, please like and subscribe for more videos like this one. :)

The Peripheral Nervous System: Nerves and Sensory Organs
We've learned about one main division of the nervous system, the central nervous system, so let's learn about the other. That's the peripheral nervous system. This is the part that receives information from your surroundings and brings it to the brain, and when the brain decides what to do, it sends signals around your body to tell it what to do. This is just as complicated as it sounds, so let's check out all the sensory organs that are involved in making this happens, as well as the nerves that transmit the information!

2-Minute Neuroscience: Touch Receptors
Touch receptors in the skin provide us with tactile information about qualities like the position, shape, texture, pressure, and movement of things we come in contact with. In this video, I discuss the four main types of touch receptors found in hairless skin.
TRANSCRIPT:
Touch receptors in the skin provide us with tactile information about qualities like the position, shape, texture, pressure, and movement of things we come in contact with. They are often classified as either rapidly-adapting or slowly-adapting. Rapidly-adapting receptors are activated when a stimulus is first encountered, but fall silent if the stimulus remains present. They are important for detecting things like movement. Slowly-adapting receptors keep responding to a continuously present stimulus and are important f...

A mechanoreceptor is a sense organ or cell that responds to mechanical stimuli such as touch, pressure, and sound.
Mechanoreceptors are responsible for the transduction of touch-related stimuli.
A thermoreceptor is a non-specialized sense receptor, or more accurately, the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.
Chemoreceptor is a sensory cell or organ responsive to chemical stimuli. They detect carbon dioxide, oxygen, and pH levels in the blood.
Electromagnetic receptors respond to light energy, for example, rods and cones.
Nociceptors are sensory receptors for painful stimuli.
They are free nerve endings located all over the body, including the skin, muscles, joints, bones, and internal organs.
The purpose of a nociceptor is to respond to body damage by transmitting signals to the spinal cord and brain.

Touch receptors in the skin provide us with tactile information about qualities like the position, shape, texture, pressure, and movement of things we come in contact with. In this video, I discuss the four main types of touch receptors found in hairless skin.
TRANSCRIPT:
Touch receptors in the skin provide us with tactile information about qualities like the position, shape, texture, pressure, and movement of things we come in contact with. They are often classified as either rapidly-adapting or slowly-adapting. Rapidly-adapting receptors are activated when a stimulus is first encountered, but fall silent if the stimulus remains present. They are important for detecting things like movement. Slowly-adapting receptors keep responding to a continuously present stimulus and are important for detecting things like the size and shape of objects. Touch receptors also vary in the size of their receptive field, or the area they can detect signals from. Having many smaller receptive fields typically allows for better tactile discrimination than fewer, large receptive fields. There are four main types of touch receptors found in hairless skin (like that of the hand).
Merkel’s discs are slowly-adapting receptors that have very small receptive fields and high spatial resolution. They are especially dense in the fingertips, and are best-suited for processing information about shape and texture.
Meissner’s corpuscles are rapidly-adapting receptors. They have relatively small receptive fields, but their spatial resolution is inferior to that of Merkel’s discs. They are especially effective at transmitting information about movement between the skin and another surface. This can be used to sense texture and to detect if an object is sliding past the skin--which is important for maintaining grip.
Pacinian corpuscles are rapidly-adapting receptors with very large receptive fields. They are thought to be most effective at transmitting information about vibrations objects cause when they are contacted or grasped by the hand. This information may be important for the use of tools.
Ruffini’s endings are slowly-adapting receptors with large receptive fields.They are poorly understood, but seem to respond most to skin stretching, like what would occur with movement of the fingers. This information might be especially important in generating awareness of finger and hand position.

The sense of touch, or tactile sense, is the perception of objects that come into contact with the skin.
Basically, mechanical stimuli such as pressure, stretch, vibration or movement, cause physical deformation in tactile receptors, which are essentially nerve endings of sensory neurons. The deformation typically leads to opening of ion channels, allowing ions to flow in or out of the cells, resulting in cellular depolarization. If the stimulus is strong enough, action potentials are generated and sent to the brain.
There are several types of tactile receptors, located in different layers of the skin and deeper tissues.
Anatomically, they can be encapsulated or unencapsulated, meaning they are wrapped or not wrapped in connective tissue, respectively.
Functionally, they can be rapidly-adapting, or slowly-adapting:
- Rapidly-adapting receptors generate action potentials when first stimulated, then quickly adapt and reduce or stop generating signals even if the stimulus continues. They respond to changes and therefore detect movements and sequence of events, rather than static objects.
- Slowly-adapting receptors, on the other hand, keep generating signals for a longer time. They carry messages about steady pressure on the skin and sense object’s texture, edges and shapes.
Touch receptors also differ in their sensitivity - some respond to light touch, others sense only heavy pressures. A sensory neuron receives signals from an area called its receptive field. Any touch within a receptive field stimulates one sensory neuron, transmitting one single signal to the brain. Being touched at 2 points within a receptive field would feel like a single touch. On the skin of the back, 2 points of contact several centimeters apart may feel like 1 touch, while on a finger, 2 contact points just 2 millimeters apart can be felt separately. Receptors with small receptive fields are more sensitive, they respond to lower frequencies of vibration; receptors with large receptive fields typically respond to higher frequencies of vibration.
A touch sensory pathway involves 3 neurons:
- Touch receptors are first-order neurons. Their axons form sensory fibers that enter the spinal cord via the dorsal root of spinal nerve.
- Inside the cord, first-order neurons synapse with second-order neurons either near the point of entry, or in the medulla of the brainstem. Second-order neurons then cross over to the other side of the cord, before ascending to the thalamus. This is how sensory information from the left side of the body is transmitted to the right side of the brain, and vice versa.
- Third-order neurons conduct the information from the thalamus to the sensory cortex.
Sensory neurons from the face and head follow several cranial nerves, mainly the trigeminal nerve, to the brainstem, where they synapse with second-order neurons, which decussate and continue to the thalamus.
The sensory cortex is spatially organized so that its adjacent areas represent neighboring regions of the body. The size of the cortical area representing a certain body region is proportional to the number of sensory receptors it has. Thus, sensitive regions with high density of receptors, such as fingers or face, have a larger cortical representation than the less sensitive trunk.
