Quizplus · Accepted Answer

The autonomic nervous system is responsible for controlling involuntary bodily functions such as breathing, heartbeat, and digestion. The somatic nervous system controls voluntary movements and sensations, while cerebrospinal fluid is a fluid that surrounds and protects the brain and spinal cord. Spinal reflexes are automatic responses to certain stimuli that bypass the brain.
