    ### Response:
    Transverse myelitis is a neurological disorder caused by inflammation across both sides of one level, or segment, of the spinal cord. The segment of the spinal cord at which the damage occurs determines which parts of the body are affected. Damage at one segment will affect function at that segment and segments below it.
