The parasympathetic nervous system is the part of the PNS that projects from only the cranial and sacral portions of the CNS. The sympathetic nervous system projects from the thoracic and lumbar portions of the CNS, while the somatic nervous system involves voluntary control of skeletal muscles. The cranial nerves are a part of the PNS, but they are not specific to the parasympathetic division. The autonomic nervous system encompasses both the sympathetic and parasympathetic divisions.
