The peripheral nervous system consists of cranial and spinal nerves that branch from the brain and spinal cord to all body parts. It is also subdivided into the somatic and autonomic systems. Cranial nerves. Twelve pairs of cranial nerves connect the brain to parts in the head, neck, and trunk.

The PNS consists of 31 pairs of spinal nerves (Fig. 2-3), which arise from the spinal cord, and 12 pairs of cranial nerves, which originate from the brainstem. In addition, the nervous system contains both the somatic system and the autonomic system, each with portions within the CNS and PNS.
Peripheral Nervous System (PNS) - Spinal nerves • Review the following on a cross section of the spinal cord and identify their function: • Anterior root - contains motor neurons • Posterior root (posterior root ganglion) - contains sensory neurons • Anterior ramus - contains both motor and sensory neurons for the body
identify the principal components of the peripheral nervous system. explain the role of the peripheral nervous system in regulating the somatic (voluntary) and autonomic (involuntary) systems. compare the functions of the sympathetic division and the parasympathetic division of the autonomic nervous system.
The nervous system is the mechanism through which the organism is kept in touch with its internal structures and external environments and reacts to changes in them. The central nervous system the brain and its caudal prolongation the spinal cord is connected to the periphery by the peripheral nervous system . The latter
