躯体神经系统(又称动物神经系统)和植物神经系统共同组成脊椎动物的周围神经系统。这部分的神经与骨骼肌的自主（有意识的）控制有关。

在周围神经系统和中枢神经系统都有躯体神经系统的成分，控制躯体的随意活动，以适应外界环境。

The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements. The SoNS consists of afferent nerves and efferent nerves. Afferent nerves are responsible for relaying sensation from the body to the central nervous system (CNS); efferent nerves are responsible for sending out commands from the CNS to the body, stimulating muscle contraction; they include all the non-sensory neurons connected with skeletal muscles and skin. The a- of afferent and the e- of efferent correspond to the prefixes ad- (to, toward) and ex- (out of).
