Question

The ________ nervous system is composed of the brain and spinal cord.
A) autonomic
B) peripheral
C) central
D) efferent
E) afferent

Accepted Answer

The central nervous system consists of the brain and spinal cord. The autonomic nervous system includes the sympathetic and parasympathetic divisions, which regulate involuntary activities. The peripheral nervous system includes all the nerves outside the brain and spinal cord, and can be further divided into the somatic and autonomic nervous systems. Efferent nerves carry signals from the central nervous system to the muscles and glands, while afferent nerves carry signals from sensory receptors to the central nervous system.
