An Introduction to Peripheral Nervous System.

  The peripheral nervous system consists of  1) Spinal nerves Thirty one pairs of spinal nerves arising from the spinal cord.  Spinal nerves are named and numbered according to the region and level of the vertebral column from which they emerge.  31 pairs of spinal nerves are distributed as. 8 pairs of cervical nerves (C 1 - C 8 ) 12 pairs of thoracic nerves (T 1 -T 12 ) 5 pairs of lumbar nerves (L 1 -L 5 ) 5 pairs of sacral nerves (S 1 -S 5 ) 1 pair of coccygeal nerve (Co 1 ) Nerve plexuses Axons of the spinal nerves (except for thoracic nerves T 2 -T 12 ) do not go directly to the body structures.  Instead, they join with various numbers of axons of adjacent nerves and form the networks on both sides of the body. Such a network of axons is called a plexus. The principal plexuses are The cervical plexus is formed by the first four cervical nerves (C 1 -C 4 ). It supplies to the skin and muscles of the head, neck and superior part of the shoulder and the chest. The brachial plexus is f
