Exam 26: Endocrine Glands

Under stress conditions, the hypothalamus is a "go between," linking the cerebrum and the pituitary.

Where is the pineal gland, and what hormone does it produce? What is the effect of this hormone?

Most of the pancreatic islets cells are alpha cells that produce insulin.

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.

The major mineralocorticoid is aldosterone.

The type of cells that secrete ACTH are:

Glucocorticoids stimulate the conversion of protein to sugar.

Tropic hormones are secreted by the acidophils of the pars anterior.

Oxytocin plays an important role in both birth and milk production.

Specific chemical-releasing factors made in the adenohypophysis are responsible for the release of ADH and oxytocin into the blood.

Prolactin is produced by the acidophils in the pars anterior.

Insulin and glucagon exert antagonistic effects on blood levels of glucose.

The anterior and posterior divisions of the pituitary develop from different embryonic structures. Identify the embryonic part from which each is derived.

What role does the hypophyseal portal system play in the control of secretions in the adenohypophysis?

Match each hormone with its structure, function, or the gland that produces it. -Hormone that lowers the concentration of glucose in the blood

The major hormone produced by the corpus luteum is LH.
