  Trigeminal nerve - Wikipedia, the free encyclopedia
The ophthalmic nerve carries sensory information from the scalp and forehead, the upper eyelid, the conjunctiva and cornea of the eye, the nose (including the tip of the nose), the nasal mucosa, the frontal sinuses and parts of the meninges (the dura and blood vessels).
The fifth nerve is primarily a sensory nerve.
From the spinal trigeminal nucleus, secondary fibers cross the midline and ascend in the trigeminothalamic tract to the contralateral thalamus.

 Sensory neuron - Wikipedia, the free encyclopedia
Sensory neurons (or neurones) are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical motor reflex loops and several forms of involuntary behavior, including pain avoidance.
In complex organisms, sensory neurons relay their information to the central nervous system or in less complex organisms, such as the hydra, directly to motor neurons and sensory neurons also transmit information to the brain, where it can be further processed and acted upon.
At the molecular level, sensory receptors located on the cell membrane of sensory neurons are responsible for the conversion of stimuli into electrical impulses.

 The Trigeminal Nerve - Wikimd   (Site not responding. Last check: 2007-10-08)
Sensory Root—The fibers of the sensory root arise from the cells of the semilunar ganglion which lies in a cavity of the dura mater near the apex of the petrous part of the temporal bone.
The ciliary ganglion is connected with the ophthalmic nerve; the sphenopalatine ganglion with the maxillary nerve; and the otic and submaxillary ganglia with the mandibular nerve.
It passes forward on the lateral side of the optic nerve, and enters the postero-superior angle of the ciliary ganglion; it is sometimes joined by a filament from the cavernous plexus of the sympathetic, or from the superior ramus of the trochlear nerve.

The optic nerve passes through the optic foramen in the skull into the orbit, where it is penetrated by the central artery of the retina, and eventually pierces the scelerotic just internal to the posterior pole of the eyeball.
Between the two ganglia the accessory part of the eleventh nerve joins the tenth, and it is from this communication that the motor twigs to the pharynx, larynx, alimentary and respiratory tracts are derived, as well as the inhibitory fibres of the heart.
The anterior tibial nerve is chiefly muscular, innervating the muscles in front of the tibia and fibula as well as the extensor brevis digitorum pedis on the dorsum of the foot, though it gives one small cutaneous branch to the cleft between the first and second toes.

 Cranial Nerve > Anatomy
The axons for the descending tract of the 5th nerve (pain and temperature) descend to the level of the upper cervical spinal cord before they synapse with neurons of the nucleus of the descending tract of the 5th nerve.
This cranial nerve has a motor component for muscles of facial expression (and, don't forget, the strapedius muscle which is important for the acoustic reflex), parasympathetics for tear and salivary glands, and sensory for taste (anterior two-thirds of the tongue).
Their sensory component is sensation for the pharynx and taste for the posterior one-third of the tongue.

 Sensory nerve neuromas--leading to failed foot surgery - Wheeless' Textbook of Orthopaedics
[JC:f3x] 7(2):110-7, 1986 Oct. Sensory nerve neuromas caused by incisions on the dorsum of the foot are a common cause of failed foot surgery and can be severely painful and disabling.
Thirty-seven patients with 55 symptomatic sensory nerve neuromas were evaluated and treated at the Painful Foot Center.
It is much easier to prevent a sensory neuroma by meticulous surgical technique than to treat a highly symptomatic neuroma.

Groups of nerve fibers are surrounded by the perineurium to form fascicles, and groups of fascicles are surrounded by the internal and external epineurium.
The MABC nerve is especially useful for surgical reconstructions in the upper extremity because all of the incisions are located in the same extremity.
The area of nerve coaptation then is immobilized for a longer time postoperatively (nerve graft for 10-14 d, nerve repair for 3 wk), although the patient is instructed in range of motion exercises for the joints proximal and distal to the immobilized region.

 Vestibulocochlear Nerve
The vestibulocochlear nerve is a sensory nerve that conducts two special senses: hearing (audition) and balance (vestibular).
The eighth nerve enters the brain stem at the junction of the pons and medulla lateral to the facial nerve.
The auditory component of the eighth nerve terminates in a sensory nucleus called the cochlear nucleus which is located at the junction of the pons and medulla.

In Hansen's disease, when the palm has a sensory change in function, the loss is usually consistent with a specific branch of the ulnar or median nerve.
Generally in more advanced involvement of the peripheral nerve branches from injury or disease, sensory and muscle function are both affected.
In the upper extremity this type of nerve involvement is generally found on the dorsum of the hands and extremities, while the warmer skin areas including the palms are spared.

The olfactory nerve is actually a collection of sensory nerve rootlets that extend down from the olfactory bulb and pass through the many openings of the cribriform plate in the ethmoid bone.
These specialized sensory receptive parts of the olfactory nerve are then located in the olfactory mucosa of the upper parts of the nasal cavity.
During breathing air molecules attach to the olfactory mucosa and stimulate the olfactory receptors of cranial nerve I and electrical activity is transduced into the olfactory bulb.

The American Diabetes Association recommends that each patient have an annual quantitative sensory test, yet prior to the availability of this testing technique standard techniques or nerve conduction studies were often not successful in detecting sensory loss at a stage of the disease early enough to successfully intervene.
The primary use of this testing includes testing for diabetic neuropathy, nerve damage associated with thyroid disease, certain vitamin deficiencies, rheumatoid arthritis, scleroderma, lupus, alcoholism, nerve entrapment disorders such as tarsal tunnel and carpal tunnel syndrome, and nerve injury associated with trauma.
The use of this device is becoming the standard of care in limb-lengthining centers, allowing for the early detection of and prevention of nerve damage associated with this type of procedure.
