Jump to: navigation, search


A nerve root is the initial segment of a nerve leaving the central nervous system. It can refer to:

  • A cranial nerve root, the beginning of one of the eleven pairs leaving the central nervous system from the brain stem or the highest levels of the spinal cord;
  • A spinal nerve root, the beginning of one of the thirty-one pairs oleaving the central nervous system from the spinal cord. Each spinal nerve root consists of the union of a sensory dorsal root and a motor ventral root.
