It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.The anterior horn cells, although technically part of the central nervous system (CNS), are sometimes discussed with the peripheral nervous system because they are part of the motor unit.ranches of the cervical and lumbosacral spinal nerves anastomose peripherally into plexuses, then branch into nerve trunks that terminate up to 1 Î¼m away in peripheral structures. The intercostal nerves are segmental. The term peripheral nerve refers to the part of a spinal nerve distal to the nerve roots.
