Multiple Choice

What effect does the parasympathetic division have on the adrenal medulla?

It causes the adrenal medulla to secrete norepinephrine only.

It inhibits the adrenal medulla from producing any hormones.

It stimulates the adrenal medulla to release epinephrine.

It has little or no direct effect on the adrenal medulla.

Verified step by step guidance

Understand the role of the parasympathetic division of the autonomic nervous system. The parasympathetic division is primarily responsible for 'rest and digest' functions, promoting relaxation, energy conservation, and maintenance of homeostasis.

Learn about the adrenal medulla's function. The adrenal medulla is part of the adrenal glands and is responsible for releasing catecholamines, such as epinephrine and norepinephrine, during the 'fight or flight' response, which is primarily controlled by the sympathetic division of the autonomic nervous system.

Recognize that the parasympathetic division does not directly stimulate the adrenal medulla. Instead, the adrenal medulla is activated by the sympathetic division during stress or emergency situations.

Review the options provided in the question. Eliminate choices that suggest direct stimulation or inhibition of the adrenal medulla by the parasympathetic division, as this is not consistent with its physiological role.

Conclude that the correct answer is: 'It has little or no direct effect on the adrenal medulla,' as the parasympathetic division does not play a significant role in adrenal medulla activity.
