Answer to Question 1

ANS: B, C, D, E
Efferent nerves leave the CNS and carry impulses to other body parts that control contractions of smooth and skeletal muscles, as well as some glandular secretions. The efferent nerves, together with afferent nerves, make up the peripheral nervous system.

Answer to Question 2

ANS: A, C, D, E
Blood pressure, GI secretion, body temperature, and urinary bladder function are body functions controlled by the autonomic nervous system. The autonomic nervous system maintains control over most tissue function, with the exception of skeletal muscle.
