What structures make up the peripheral nervous system?

Cranial and spinal nerves that connect the CNS to the rest of the body.

Distinguish between the somatic and autonomic nervous systems in terms of function.

The somatic nervous system controls voluntary movements of skeletal muscles; the autonomic nervous system controls involuntary functions of internal organs.

What does the somatic nervous system control?

Voluntary movements by innervating skeletal muscles.

What are the two divisions of the autonomic nervous system?

The sympathetic and parasympathetic divisions.
