Final answer:
The peripheral nervous system consists of somatic and autonomic structures, as well as the enteric nervous system.
Step-by-step explanation:
The peripheral nervous system (PNS) consists of both somatic and autonomic structures, as well as the enteric nervous system.
Somatic structures include the spinal nerves, both motor and sensory fibers, as well as the sensory ganglia (posterior root ganglia and cranial nerve ganglia). Autonomic structures are also found in the nerves, but include the sympathetic and parasympathetic ganglia. The enteric nervous system includes the nervous tissue within the organs of the digestive tract.
