Answer :
Final answer:
The peripheral nervous system includes the somatic nervous system, the sympathetic nervous system, and the parasympathetic nervous system, but not the spinal cord, which is part of the central nervous system.
Explanation:
The peripheral nervous system (PNS) is the part of the nervous system that lies outside the central nervous system (CNS). The CNS includes the brain and spinal cord, which is not part of the PNS. The PNS itself includes several components, including the somatic nervous system, autonomic nervous system (which comprises the sympathetic and parasympathetic nervous systems), cranial nerves, spinal nerves, and peripheral nerves. Therefore, when discussing parts that belong to the peripheral nervous system, we include the somatic nervous system, the sympathetic nervous system, and the parasympathetic nervous system.
Cranial nerves, ganglia, and spinal nerves are part of the peripheral nervous system.
One of the two parts that make up the nervous system of bilateral animals is the peripheral nervous system "PNS" and the other part is the central nervous system "CNS". In addition to the brain and spinal cord, the PNS consists of nerves and ganglia.
The main function of the PNS is to transmit information between the brain and spinal cord and the rest of the body by connecting the CNS to limbs and organs. Unlike the central nervous system, the peripheral nervous system is not protected by the blood-brain barrier, the spine, or the skull.
