Answer to Problem 14A

Correct answer:

The correct answer is option (D) autonomic.

Explanation of Solution

Explanation/justification for the correct answer:

Option (D) autonomic. The autonomic nervous system is connected with the hypothalamus that is involved in the regulation of the involuntary activities. It regulates heart rate, blood pressure, and functions of other internal organs. So, this is the correct answer.

Explanation for incorrect answer:

Option (A) voluntary. The voluntary nervous system does not involve regulation by the hypothalamus. It controls the voluntary movements and connects the central nervous system to the muscles of the body. So, this is an incorrect option.

Option (B) peripheral. The peripheral nervous system consists of the somatic nervous system and autonomic nervous system. The autonomic nervous system involves regulating. The peripheral nervous system as a whole is not involved in regulation. So, this is an incorrect option.

Option (C) sensory. The sensory nervous system converts the external stimuli into the internal impulses. The sensory nervous system is not involved in regulation and is not the hypothalamus. So, this is an incorrect answer.
