Sensory nerve
A sensory nerve is a nerve that carries sensory information toward the central nervous system (CNS). It is an enclosed, cable-like bundle of afferent nerve fibers (the axons of sensory neurons) in the peripheral nervous system (PNS). These fibers link sensory receptors on the body surface or in the tissues to relevant processing circuits in the CNS. Sensory nerves are often paired with motor nerves, which are bundles of efferent nerve fibers that travel from the CNS to the PNS. Stimuli cause nerve impulses in the receptors and alter the potentials, which is known as sensory transduction.
Input into the CNS
Types of Sensory Receptors
For a signal to be sent down the sensory nerve, it must first be transduced from an external stimulus into action potential. This occurs at the site of the sensory receptors. There are different kinds of sensory receptors that respond to different stimuli. These sensory receptors include chemorecptors, photoreceptors, mechanoreceptors, thermoreceptors, and nociceptors. The different receptors respond to the different stimuli exist and transduce the energies into action potentials that are generated at the sensory neuron.

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!

Sensory neurons
Tactility, the totality of what we feel with our senses of touch, pain, pressure, heat, cold, even itch and tickle. Its all generated by transaction, where the stimulus from the external environment is converted into a coded electrical series of impulses. Next there is neurological transmission, followed by the sensation being operationalised into consciousness in the sensory cortex of the brain, in the post central gyrus of the parietal lobe where left feels right and right feels left.

The function of the nervous system is to provide rapid communication and integration between various organs, as well as with the outside environment. Fast communication is achieved by means of electrical signals, known as nerve impulses, which are generated and carried by specialized cells, called neurons.
The major components of the nervous system are the brain, spinal cord and nerves. The brain, enclosed and protected in the cranium, is the central processing center. The spinal cord, enclosed in the spinal column, functions as a communication gateway between the brain and the trunk and limbs. Nerves are composed of axons of neurons, the cell bodies of which are clustered in knot-like structures called ganglia. Ganglia commonly serve as relay centers, where neurons synapse and transmit information to each other.
The brain and spinal cord make up the central nervous system, while nerves and ganglia constitute the peripheral nervous system.
Sensory nerve fibers carry sensory information from sensory receptors to the central nervous system, while motor nerves conduct motor instructions from the central nervous system to effector organs – the muscles and glands. Nerves that contain both sensory and motor fibers are known as mixed nerves.
There are 2 major groups of nerves: cranial nerves and spinal nerves:
- The 12 pairs of cranial nerves emerge from the base of the brain and relay information between the brain and the head and neck regions. The cranial nerve X, named vagus nerve, also communicates with internal organs.
- The 31 pairs of spinal nerves arise from segments of the spinal cord and innervate the trunk and limbs. Spinal nerves communicate with the brain via the spinal cord. All spinal nerves are mixed nerves, they contain both sensory and motor fibers. Typically, sensory receptors send impulses by way of sensory fibers in spinal nerves, to the spinal cord, which relays the information up to the brain. The brain interprets the information and sends back instructions, down the spinal cord, to motor fibers in spinal nerves, to reach effector organs.
The peripheral nervous system can be divided into somatic and visceral subdivisions. The somatic nervous system includes sensory nerves from the skin, muscles, bones and joints; and motor nerves that innervate skeletal muscles. This system controls voluntary muscular contractions, as well as involuntary somatic reflexes. The visceral nervous system, on the other hand, includes sensory division that detects changes in the viscera – the organs in the thoracic and abdominal cavities; and motor division that controls cardiac muscle, smooth muscle of internal organs and glands. It produces, for example, faster heart rate and breathing rate during physical exercise, and slower cardiorespiratory rate during sleep. The visceral motor division is also known as the autonomic nervous system because it is largely autonomous, acting independently of the body’s consciousness and voluntary control.

ABSTRACT
The superficial radial sensory nerve can be entrapped between the brachioradialis and extensor carpi radialis longus tendons as the radial sensory nerve courses superficially from its deep origin. Compression of the radial sensory nerve presents with numbness and/or pain on the dorsal radial aspect of the hand. Pronation of the hand exacerbates these symptoms as the interval between these two tendons decreases. Decompression of the radial sensory nerve involves a muscle tenotomy of the brachioradialis tendon. The brachioradialis is expendable as the biceps brachii and brachialis provides redundant function for elbow flexion. The lateral antebrachial cutaneous nerve has a superficial course to the radial sensory nerve and the branches of this nerve are protected during decompression. In this case, the patient presented with a radial nerve palsy nine months following a humeral fracture treated with an open reduction and internal fixation. Electrodiagnostic studies revealed fibrillations and motor unit potentials predicting recovery of the radial nerve. A posterior interosseous nerve release was performed and the patient recovered radial motor nerve function thereafter, however the patient continued with complaints of numbness and tingling in the radial sensory nerve territory. Provocative tests were elicited at the radial sensory nerve entrapment point and the patient underwent the decompression of the radial sensory nerve by neurolysis and tenotomy of the brachialis tendon.

The function of the nervous system is to provide rapid communication and integration between various organs, as well as with the outside environment. Fast communication is achieved by means of electrical signals, known as nerve impulses, which are generated and carried by specialized cells, called neurons.
The major components of the nervous system are the brain, spinal cord and nerves. The brain, enclosed and protected in the cranium, is the central processing center. The spinal cord, enclosed in the spinal column, functions as a communication gateway between the brain and the trunk and limbs. Nerves are composed of axons of neurons, the cell bodies of which are clustered in knot-like structures called ganglia. Ganglia commonly serve as relay centers, where neurons synapse and transmit information to each other.
The brain and spinal cord make up the central nervous system, while nerves and ganglia constitute the peripheral nervous system.
Sensory nerve fibers carry sensory information from sensory receptors to the central nervous system, while motor nerves conduct motor instructions from the central nervous system to effector organs – the muscles and glands. Nerves that contain both sensory and motor fibers are known as mixed nerves.
There are 2 major groups of nerves: cranial nerves and spinal nerves:
- The 12 pairs of cranial nerves emerge from the base of the brain and relay information between the brain and the head and neck regions. The cranial nerve X, named vagus nerve, also communicates with internal organs.
- The 31 pairs of spinal nerves arise from segments of the spinal cord and innervate the trunk and limbs. Spinal nerves communicate with the brain via the spinal cord. All spinal nerves are mixed nerves, they contain both sensory and motor fibers. Typically, sensory receptors send impulses by way of sensory fibers in spinal nerves, to the spinal cord, which relays the information up to the brain. The brain interprets the information and sends back instructions, down the spinal cord, to motor fibers in spinal nerves, to reach effector organs.
The peripheral nervous system can be divided into somatic and visceral subdivisions. The somatic nervous system includes sensory nerves from the skin, muscles, bones and joints; and motor nerves that innervate skeletal muscles. This system controls voluntary muscular contractions, as well as involuntary somatic reflexes. The visceral nervous system, on the other hand, includes sensory division that detects changes in the viscera – the organs in the thoracic and abdominal cavities; and motor division that controls cardiac muscle, smooth muscle of internal organs and glands. It produces, for example, faster heart rate and breathing rate during physical exercise, and slower cardiorespiratory rate during sleep. The visceral motor division is also known as the autonomic nervous system because it is largely autonomous, acting independently of the body’s consciousness and voluntary control.

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!

Tactility, the totality of what we feel with our senses of touch, pain, pressure, heat, cold, even itch and tickle. Its all generated by transaction, where the stimulus from the external environment is converted into a coded electrical series of impulses. Next there is neurological transmission, followed by the sensation being operationalised into consciousness in the sensory cortex of the brain, in the post central gyrus of the parietal lobe where left feels right and right feels left.

ABSTRACT
The superficial radial sensory nerve can be entrapped between the brachioradialis and extensor carpi radialis longus tendons as the radial sensory nerve courses superficially from its deep origin. Compression of the radial sensory nerve presents with numbness and/or pain on the dorsal radial aspect of the hand. Pronation of the hand exacerbates these symptoms as the interval between these two tendons decreases. Decompression of the radial sensory nerve involves a muscle tenotomy of the brachioradialis tendon. The brachioradialis is expendable as the biceps brachii and brachialis provides redundant function for elbow flexion. The lateral antebrachial cutaneous nerve has a superficial course to the radial sensory nerve and the branches of this nerve are protected during decompression. In this case, the patient presented with a radial nerve palsy nine months following a humeral fracture treated with an open reduction and internal fixation. Electrodiagnostic studies revealed fibrillations and motor unit potentials predicting recovery of the radial nerve. A posterior interosseous nerve release was performed and the patient recovered radial motor nerve function thereafter, however the patient continued with complaints of numbness and tingling in the radial sensory nerve territory. Provocative tests were elicited at the radial sensory nerve entrapment point and the patient underwent the decompression of the radial sensory nerve by neurolysis and tenotomy of the brachialis tendon.

Sensory nerve
A sensory nerve is a nerve that carries sensory information toward the central nervous system (CNS). It is an enclosed, cable-like bundle of afferent nerve fibers (the axons of sensory neurons) in the peripheral nervous system (PNS). These fibers link sensory receptors on the body surface or in the tissues to relevant processing circuits in the CNS. Sensory nerves are often paired with motor nerves, which are bundles of efferent nerve fibers that travel from the CNS to the PNS. Stimuli cause nerve impulses in the receptors and alter the potentials, which is known as sensory transduction.
Input into the CNS
Types of Sensory Receptors
For a signal to be sent down the sensory nerve, it must first be transduced from an external stimulus into action potential. This occurs at the site of the sensory receptors. There are different kinds of sensory receptors that respond to different stimuli. These sensory receptors include chemorecptors, photoreceptors, mechanoreceptors, thermoreceptors, and nociceptors. The different receptors respond to the different stimuli exist and transduce the energies into action potentials that are generated at the sensory neuron.
