The ventral rami of spinal nerves form plexuses. A plexus is a network of nerves that arise from the ventral rami of spinal nerves after they leave the intervertebral canal.
The ventral rami of spinal nerves form plexuses and supply the muscles of the limbs. The network of nerve fibers that originate from the ventral rami of spinal nerves and the autonomic nervous system forms the plexus.Nerves that emerge from the ventral rami and pass through plexuses supply the muscles and skin of the limbs and trunk. The primary function of a nerve plexus is to provide sensory and motor innervation to the limbs and trunk of the body.
The motor neurons of the plexus distribute impulses to the muscles of the limbs, while the sensory neurons convey sensory information from the skin of the limbs and trunk to the central nervous system.
