syndrome characterized by absensce of fever pain, tenderness, motor weakness, and absence of tendon reflexes. A type of encephalitis
Radiculoneuritis
interruption of nerve roots in spinal canal
Rhizotomy
compression of brachial plexus resulting in pain to the arms, numbness of fingers and wasting of the muscles of the hand
thoratic outlet syndrome
benign tumor with auditory canal arising from the VIII crcanial (acustic) nerve
Acoustic neuroma
benign tumor of peripheral nerves due to abnormal proliferation or schwann cells AKA fibroneuroma
neurofibroma
neurofibromatosis characterized by developement changes of various body sys including the nervous sys. characterized by formation of neurofibromas over the entire body assosiated with patches of pigmentation

tumor of peripheral nerve sheath (neurilemma AKA schwannome)
neurilemona
sarcomma derived from nervous tissue chiefly neuroblasts primarily affects young children usually arising in ANS
neuroblastoma
idiopathic polneuritis characterized by wide-spread patchy demylinetion of spinal nerve and nerve roots with some imflamatory chang symptoms... muscular weakness in legs to trunks, slow recovery
guillbin-barre syndrome
inflation of spinal nerves characterized by muscular weakness numbness, tingling, tenderness and pain caused by systemic chronic disorder such as diabetics alcoholism etc
peripheral neuritis
acute vial infection manifested along sensory root ganglia and caused by herpes simplex virus. Disease exibits vesticular eruptions along area of distribution of the sensory nerve.
