The cell clusters in the zona glomerulosa produce ______.

mineralocorticoids

Which of the following homeostatic imbalances usually results from deficits in both glucocorticoids and mineralocorticoids?

Addison's disease

What gland would produce the hormone needed to restore homeostasis when you have loss of Na+ from profuse sweating?

Adrenal cortex

Identify the part of the adrenal gland indicated by "E."

Adrenal medulla

If you have a homeostatic imbalance of excessive loss of Na+ in extracellular fluids, what hormone will help restore that balance?

Aldosterone

Which of the following hormones is secreted by the adrenal cortex?

Aldosterone

Match the following hormone with its function: Melatonin.

Associated with drowsiness at night

What hormone would be released in response to a rise in blood pressure?

Atrial natriuretic peptide

Cortisol belongs to which category of hormones?

Glucocorticoids

Androgens secreted by the adrenal cortex belong to which category of hormones?

Gonadocorticoids

Which of the following hormones is secreted by the adrenal gland?

Cortisol

What is the function of the glucocorticoids?

Increase blood levels of glucose, fatty acids, and amino acids during stress

What is the function of aldosterone?

Increases Na+ reabsorption in the kidneys

The pineal gland secretes which hormone?

Melatonin

Identify a function of gonadocorticoids.

Produce masculinizing effects when produced in large quantities
