Exam 19: Endocrine Glands

Thymosin is a hormone that plays a role in:

Diabetics produce an excessive amount of insulin.

The first step in the renin-angiotensin mechanism is:

Glucagon,produced by alpha cells,tends to promote the movement of glucose,amino acids,and fatty acids out of the blood and into tissue cells.

Match each hormone with its structure, function, or the gland that produces it. -hormone that causes an increase in blood calcium levels

Match each hormone with its structure, function, or the gland that produces it. -hormone that is a chief glucocorticoid released by the adrenal gland

The center of the adrenal gland is the cortex.

Explain the negative feedback principle for controlling anterior pituitary tropic hormone production.Give an example in your explanation.

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

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

Calcitonin inhibits the functioning of osteoblasts.

Match each hormone with its corresponding description. -also known as prolactin

Match each hormone with its structure, function, or the gland that produces it. -calcium-regulating hormone that is made in the thyroid gland

Prolactin is produced by the acidophils in the pars anterior.

The thyroid functions to support the body's biological clock.

Hypersecretion of prolactin can cause impotence in men.

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

Because the target organs of follicle-stimulating hormone and luteinizing hormone are organs of the female reproductive system,males do not produce them.

The thyroid hormone T₃ is more potent than T₄ but less of it is produced.

Hypercalcemia may be a cause of muscle spasms.
