Answer the questions that follow. 1 The motor division of the peripheral nervous system is composed of two independent systems—the somatic nervous system and the autonomic nervous system. 2 The somatic nervous system consists of motor neurons that control the movement of skeletal muscles. 3 The somatic system is said to be voluntary—that is, skeletal muscles can be moved at will. 4 The somatic system can also operate without conscious control, as it does when you maintain your balance. 5 The autonomic nervous system consists of nerves that control the body’s internal conditions by regulating smooth muscles, both in blood vessels and in organs. 6 The autonomic nervous system controls respiration, heartbeat, digestion, and other functions of homeostasis.</p><p>Read each question and write your answer in the space provided.
