Cranial nerves are those arising from the BRAIN.... cranial nerves

A set of 31 pairs of nerves that connect to the spinal cord. Spinal nerves emerge in 2 rows from either side of the spinal cord and leave the spine through gaps between adjacent vertebrae. The nerves then branch out to supply all parts of the trunk, arms, and legs with sensory and motor nerve fibres.

Disc prolapse may lead to pressure on a spinal nerve, causing pain. Injury to a nerve may lead to loss of sensation or movement in the area supplied by the nerve. (See also nerve injury; neuropathy.)... spinal nerves

These have several causes. Continued or repeated severe pressure may damage a nerve seriously, as in the case of a crutch pressing into the armpit and causing drop-wrist. Bruising due to a blow which drives a super?cially placed nerve against a bone may damage, say, the radial nerve behind the upper arm. A wound may sever nerves, along with other structures; this accident is specially liable to occur to the ulnar nerve in front of the wrist when a person accidentally puts a hand and arm through a pane of glass.

Symptoms When a sensory nerve is injured or diseased, sensation is immediately more or less impaired in the part supplied by the nerve. Ulceration or death of the tissue supplied by the defective nerve may occur. When the nerve in question is a motor one, the muscles governed through it are instantly paralysed. In the latter case, the portion of nerve beyond the injury degenerates and the muscles gradually waste, losing their power of contraction in response to electrical applications. Finally, deformities result and the joints become ?xed. This is particularly noticeable when the ulnar nerve is injured, the hand and ?ngers taking up a claw-like position. The skin may also be affected.

Treatment Damaged or severed (peripheral) nerve ?bres should be sewn together, using microsurgery. Careful realignment of the nerve endings gives the ?bres an excellent chance of regenerating along the right channels. Full recovery is rare but, with regular physiotherapy to keep paralysed muscles in good shape and to prevent their shortening, the patient can expect to obtain a reasonable return of function after a few weeks, with improvement continuing over several months.... nerves, injuries to

Nerve damage can include neuropathy or neuritis, which can be caused by diabetes, nerve injury, autoimmune disease, viral infections, muscle spasms or vitamin deficiencies. Traditional medicine found a lot of treatments for nerve damage, but alternative medicine fans think that you don’t need to take a lot of pills for something that can be treated with just a cup of tea.

Don’t take more than 2 cups per day for a short amount of time and don’t combine it with anti-depressants and sedatives. Basil Tea – this Tea for Nerves has many medical uses and not only that it can repair the nervous ailments, but it’s also a great energy and health enhancer.

sympathetic nerves that supply muscle fibres in the skin, around the roots of hairs. Activity of the sympathetic nervous system causes the muscles to contract, raising the hairs and giving the *gooseflesh effect of fear or cold.... pilomotor nerves

(caudal regression syndrome) a severe neural tube defect specific to diabetic pregnancies. The risk may be correlated with the *glycated haemoglobin (HbA1c) level.... sacral agenesis

Small nerve ?bres that lie upon the walls of blood vessels and connect the muscle ?bres of their middle coat with the NERVOUS SYSTEM. Through these nerves the blood vessels are retained in a state of moderate contraction. There are vasodilator nerves, through which are transmitted impulses that dilate the vessels, and, in the case of the skin vessels, produce the condition of blushing; there are also vasoconstrictor nerves which transmit impulses that constrict, or narrow, the blood vessels – as occurs on exposure to cold (see HYPOTHERMIA). Various drugs produce dilatation or contraction of the blood vessels, and several of the substances produced by ENDOCRINE GLANDS in the body have these effects: for example, ADRENALINE.... vasomotor nerves
