Exam 26: Endocrine Glands

ACTH stimulates the adrenal medulla to produce and secrete its hormones.

The hormone most likely to cause a shift from glucose catabolism to fat catabolism is:

Match each hormone with its corresponding description. -Secreted by the corpus luteum

Growth hormone has a hyperglycemic effect.

Ghrelin functions to reduce appetite and prevent an increase in blood glucose level.

The adrenal medulla functions as postganglionic sympathetic neurons. They are even stimulated by preganglionic sympathetic neurons.

Aldosterone influences the kidney tubules to retain sodium and potassium ions.

PTH increases calcium absorption in the intestines by activating vitamin D.

FSH and LH are called gonadotropins because they stimulate the growth and maintenance of the gonads.

The renin-angiotensin mechanism is a negative-feedback mechanism that helps maintain homeostasis of blood calcium levels.

Calcitonin acts to increase blood calcium levels.

Unlike thyroid hormone, calcitonin is said to have a "general" target.

High levels of hCG in the body would indicate:

Match each hormone with its structure, function, or the gland that produces it. -Hormone that is produced by the alpha cells of the pancreas

Calcitonin inhibits the functioning of osteoblasts.

The anterior pituitary develops from the upward projection of the pharynx.

Glucocorticoids have a hypoglycemic effect on blood sugar.

Secretion of _____ is controlled mainly by the renin-angiotensin mechanism and blood potassium concentration.

Cortisone is the only glucocorticoid that is secreted in significant quantities.

The mineralocorticoids of the adrenal cortex regulate or influence _____ balance.
