Definition of spinal nerves in English English dictionary

There are 31 pairs of spinal muscles: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal They are all mixed nerves attached to the spinal cord by a dorsal root composed on sensory fibres and a ventral root composed of motor fibres Except for the thoracic nerves T2-T12, the ventral rami of the spinal nerves combine and then split again as networks of nerves known as plexuses There are four such plexuses, but only one, the cervical plexus is of concern to us

24 pairs of nerves exiting from the spinal cord at segmental levels of the spinal column

thirty-one pairs of mixed nerves (sensory and motor) that are second order lower motor neurons and form part of the final common pathway; they also form a reflex arc; their motor fibers originate on the ventral part of the spinal cord at the anterior horns of grey matter and their roots of sensory fibers are located on the dorsal side of the spinal cord in the posterior root ganglia; these join together to form the spinal nerves after they exit the spinal column; the spinal nerves receive only contralateral innervation from first order neurons
