Question

A group of students is reviewing material about endocrine system function. The students demonstrate an understanding of the information when they identify which of the following is secreted by the adrenal medulla?

a. Glucocorticoids
b. Mineralocorticoids
c. Glucagon
d. Epinephrine

Answer 1

d. Epinephrine

Step-by-step explanation:

The adrenal glands which are located at the top of each kidney are made up of two parts: the cortex and the medulla.

The adrenal cortex is the outer part of the adrenal gland, while the inner part is the adrenal medulla.

The adrenal medulla has tissues that are composed of popstganglionic sympathetic nervous system neurons which are involved in stimulating the medulla to secrete the epinephrine and norepinephrine hormones.

Epinephrine functions to increase cardiac output and increase level of glucose in the blood when the body is exposed to threat or stress.
