The musculocutaneous nerve, from C5, C6, C7, is the main supplier of muscles of the anterior compartment.

The brachialis muscle is innervated by the musculocutaneous nerve, which runs on its superficial surface, between it and the biceps brachii.

* The musculocutaneous nerve innervates all the muscles of the anterior compartment of the arm.

The musculocutaneous nerve presents frequent variations.

A relatively new technique involving a graft from the side of the chest under the armpit ( known as a musculocutaneous latissimus dorsi free transfer flap ) is a step forward in phalloplasty.

2. Some of the fibers of the median may run for some distance in the musculocutaneous and then leave it to join their proper trunk ; less frequently the reverse is the case, and the median sends a branch to join the musculocutaneous.

* The branches to the Biceps brachii and Brachialis are given off after the musculocutaneous has pierced the Coracobrachialis ; that supplying the Brachialis gives a filament to the elbow-joint.

Although rare, the musculocutaneous n. can be affected through compression due to hypertrophy or entrapment between the biceps aponeurosis and brachialis fascia or it may be injured through stretch as occurs in dislocations and sometimes in surgery.

The phrenic nerve arises from nerve roots C3, C4 and C5.

* dysfunction: another complication arises when the herniated organ itself, or surrounding organs, start to malfunction ( for example, sliding hernia of the stomach causing heartburn, lumbar disc hernia causing sciatic nerve pain, etc.

The clinical underpinnings of two of the most common spasticity conditions, spastic diplegia and multiple sclerosis, can be described as follows: in spastic diplegia, the upper motor neuron lesion arises often as a result of neonatal asphyxia, while in conditions like multiple sclerosis, spasticity is thought by some to be as a result of the autoimmune destruction of the myelin sheaths around nerve endings — which in turn can mimic the gamma amino butyric acid deficiencies present in the damaged nerves of spastic diplegics, leading to roughly the same presentation of spasticity, but which clinically is fundamentally different from the latter.

Posteriorly, this fascial origin corresponds, more or less closely, with the tendinous arch of the pelvic fascia, but in front, the muscle arises from the fascia at a varying distance above the arch, in some cases reaching nearly as high as the canal for the obturator vessels and nerve.

Without this Hoxb-1 expression, a nerve which is similar to the trigeminal nerve arises.

The motor part of the facial nerve arises from the facial nerve nucleus in the pons while the sensory part of the facial nerve arises from the nervus intermedius.

The median nerve arises from the cubital fossa and passes between the two heads of pronator teres.

The unbranched portion of the median nerve ( which arises from the cubital fossa ) innervates muscles of superficial and intermediate groups of the anterior compartment except flexor carpi ulnaris.

* The palmar cutaneous branch of the median nerve arises at the distal part of the forearm.

The cephalic vein arises within the anatomical snuffbox, while the dorsal cutaneous branch of the radial nerve can be palpated by stroking along the extensor pollicis longus with the dorsal aspect of a fingernail.

The oculomotor nerve ( CN III ) arises from the anterior aspect of mesencephalon ( midbrain ).

The nerve arises from the hypoglossal nucleus and emerges from the medulla oblongata in the preolivary sulcus separating the olive and the pyramid.

This nerve arises from between the first and second cervical vertebrae, along with the lesser occipital nerve.

It arises from the lateral branch of the ventral ramus of the second cervical nerve, sometimes also from the third ; it curves around and ascends along the posterior border of the Sternocleidomastoideus.

The phrenic nerve arises from the neck ( C3-C5 ) and innervates the diaphragm, which is much lower.

The dorsal scapular nerve arises from the brachial plexus, usually from the plexus root ( anterior / ventral ramus ) of C5.

This nerve characteristically arises by three roots from the fifth, sixth, and seventh cervical nerves ( C5-C7 ) but the root from C7 may be absent.

They are distinguished by the nerve cells affected ( upper and lower motor neuron ), and the symptoms that result from this damage:

An axon ( also known as a nerve fiber ) is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body.

The longest axons in the human body, for example, are those of the sciatic nerve, which run from the base of the spine to the big toe of each foot.

Mammalian axonal arborization ( the branching structure at the end of a nerve fiber ) also differs from one nerve fiber to the next.

The fundamental bilateral body form is a tube with a hollow gut cavity running from the mouth to the anus, and a nerve cord with an enlargement ( a ganglion ) for each body segment, with an especially large ganglion at the front, called the brain.

Two groups of invertebrates have notably complex brains: arthropods ( insects, crustaceans, arachnids, and others ), and cephalopods ( octopuses, squids, and similar molluscs ).< ref name = Butler > The brains of arthropods and cephalopods arise from twin parallel nerve cords that extend through the body of the animal.

When brain tissue from a CJD patient is examined under a microscope, many tiny holes can be seen where whole areas of nerve cells have died.

Damage to the ulnar nerve in the palm, carpal tunnel in the wrist, the genitourinary tract or bicycle seat neuropathy may result from overuse.

Some cyclists with induced pudendal nerve pressure neuropathy gained relief from improvements in saddle position and riding techniques.

For example, varicella zoster virus causes chickenpox in the acute phase ; after recovery from chickenpox, the virus may remain dormant in nerve cells for many years, and later cause herpes zoster ( shingles ).

These ganglion cells, which contain melanopsin, convey their signals to the " circadian clock " via the retinohypothalamic tract ( distinct from the optic nerve ), linking the retina to the pineal gland.

Surgical interventions for IC / BPS include transurethral fulguration and resection of ulcers, using electricity / laser ; bladder denervation, where some of the nerves to the bladder are cut ( Modified Ingelman-Sundberg Procedure ); bladder augmentation ; bladder removal ( cystectomy ); electrical nerve stimulation, similar to TENS, where an electrical unit is implanted in the body and provides continuous or intermittent electrical pulses to the affected areas ( Interstim ); spinal cord stimulation ( SCS ), where an electrical unit is implanted that provides electrical stimulation to the spinal cord, interfering with pain reception to the brain ( ANS / Advanced Neuromodulation Systems spinal Cord Stimulator ); and the implantation of the intrathecal pain pump, where very small amounts of medication, like morphine sulfate, dilaudid, or baclofen are released into the cerebrospinal fluid via a catheter stemming from the small electrical pump, requiring only about 1 / 100 to 1 / 300 the amount of medication needed orally for the same therapeutic benefit, but with significantly fewer side effects.

Afterwards, the radioactive debris and soils were placed in a landfill on the island, along with residue from Agent Orange containers returned from Southeast Asia after the Vietnam War, PCBs, PAHs, dioxins, and sarin nerve gas from the Soviet Union and East Germany.

In addition to bouts with malaria, battle wounds from fighting in the Mexican-American War, and a chronic eye infection that made it impossible for him to endure bright light, he also suffered from trigeminal neuralgia, a nerve disorder that causes severe pain in the face.

The kidney also receives input from the parasympathetic nervous system, by way of the renal branches of Vagus nerve ( Cranial nerve X ), the function of this is yet unclear.

Marvin's wound ( in the buttocks ) was from machine gun fire, which severed his sciatic nerve.

Gas tends to rise, and when a pocket of CO < sub > 2 </ sub > rises in the abdomen, it pushes against the diaphragm ( the muscle that separates the abdominal from the thoracic cavities and facilitates breathing ), and can exert pressure on the phrenic nerve.

In normal neuromuscular function, a nerve impulse is carried down the axon ( the long projection of a nerve cell ) from the spinal cord.
