  • Nerve root

    serch.it?q=Nerve-root

    A nerve root (Latin: radix nervi) is the initial segment of a nerve leaving the central nervous system. Types include: A cranial nerve root is the initial or proximal segment of one of the twelve pairs of cranial nerves leaving the central nervous system from the brain stem or the highest levels of the spinal cord. A spinal nerve root is the initial or proximal segment of one of the thirty-one pairs of spinal nerves leaving the central nervous system from the spinal cord. Each spinal nerve is formed by the union of a sensory dorsal root and a motor ventral root, meaning that there are sixty-two dorsal/ventral root pairs, and therefore one hundred and twenty four nerve roots in total, each of which stem from a bundle of nerve rootlets (or root filaments).

  • Alcoholic polyneuropathy

    serch.it?q=Alcoholic-polyneuropathy

    Alcoholic polyneuropathy (A.K.A alcohol leg) is a neurological disorder in which peripheral nerves throughout the body malfunction simultaneously. It is defined by axonal degeneration in neurons of both the sensory and motor systems and initially occurs at the distal ends of the longest axons in the body. This nerve damage causes an individual to experience pain and motor weakness, first in the feet and hands and then progressing centrally. Alcoholic polyneuropathy is caused primarily by chronic alcoholism; however, vitamin deficiencies are also known to contribute to its development. This disease typically occurs in chronic alcoholics who have some sort of nutritional deficiency. Treatment may involve nutritional supplementation, pain management, and abstaining from alcohol.

  • Discitis

    serch.it?q=Discitis

    Discitis or diskitis is an infection in the intervertebral disc space that affects different age groups. In adults it can lead to severe consequences such as sepsis or epidural abscess but can also spontaneously resolve, especially in children under 8 years of age. Discitis occurs post surgically in approximately 1-2 percent of patients after spinal surgery.
