secretes ACTH, TSH, and gonadotropins

T3, T4, and calcitonin are

secreted by the thyroid gland.

Insulin and glucagon

are secreted by the pancreas and are concerned with the regulation of blood glucose.

The islets of Langerhans

secrete insulin and glucagon.

Steroids

include the glucocorticoids, mineralocorticoids, and androgens.

The adrenal medulla

is part of the "fight-or-flight" response.

Iodine containing hormones

regulate metabolic rate.

Antidiuretic hormone (ADH) and oxytocin

stimulate the kidney to excrete Na+ and water.

Portal capillaries carry releasing hormones from the brain to the

anterior pituitary gland.

Which of the following is the response to low plasma levels of calcium?

secretion of PTH

What is the stimulus for the release of insulin?

high plasma levels of glucose

The adenohypophysis

refers to the anterior pituitary gland

This gland secretes TSH, ACTH, and growth hormone.

anterior pituitary gland

The adrenal cortex

secretes catecholamines

This gland is associated with "sugar, salt, and sex."

adrenal cortex

Which of the following is least associated with the adrenal medulla?

sugar, salt sex

Catecholamines

include epinephrine (adrenaline) and norepinephrine

Enlargement of the thyroid gland

goiter

"Sugar, salt, and sex" is descriptive of

cortisol, aldosterone, testosterone

stimulates the mammary glands to make milk

Which of the following is not controlled by a hypothalamic-releasing hormone?

ADH

are secreted by the gonads

Testosterone is best described as

adenohypophyseal

portal capillaries

Which of the following hormones are found within the hypophyseal hypothalamic portal capillaries?

releasing hormones

second chemical messenger

TSH

is secreted by the anterior pituitary gland

The only hormone that lowers blood glucose is

insulin

PTH

stimulates osteoblastic activity and causes blood calcium to increase

Insulin

is secreted by the beta cells of the islets of Langerhans

ACTH stimulates the

adrenal cortex to secrete cortisol.

negative feedback control

Which of the following steroids is an androgen?

testosterone

Which of the following is a function of parathyroid hormone?

It increases plasma levels of calcium

Cretinism, myxedema, and Graves' disease are all
