Figurę 2.14 Peripheral Neryous System

The peripheral nervous system (PNS) COnsiSIS of all ot the neural ele-ments outside ot the CNS (brain and spinał cord) and provides the connections between the CNS and all other body organ systems. TIu* PNS consisls of somalic hihJ autonomie eomponents. Tłte somatic component innervates skeletal musde and skin and is shown here (see Figurę 2.1 S for the autonomie nervous system). The somatic component of the peripheral nerves contains both motor and sensory axons. Celi bodies of the motor neurons are found in the anlerior horn gray matter, whereas the celi bodies of sensory neurons are located in the dorsal root ganglia.
