Exam 26: Endocrine Glands

The pituitary gland fits in the pituitary fossa in a structure called the sella turcica.

Hormones of the neurohypophysis are actually made by cells of the supraoptic or sella turcica nuclei.

The neurohypophysis serves as a storage and release site for:

The release of ADH and oxytocin is controlled by nervous stimulation.

The pineal gland is part of two systems, the endocrine system and the nervous system.

Calcitonin decreases calcium storage in bones, thereby raising blood calcium levels.

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

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

When the amount of ADH increases, the body tries to get rid of excess fluid and the volume of urine increases.

Glucocorticoids have a hypoglycemic effect on blood sugar.

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

LH is an example of a tropic hormone.

Select a hormone that would cause a problem for the body if it were hyposecreted or hypersecreted. Name and describe the conditions caused by both hyposecretion and hypersecretion of that hormone.

Insulin and glucagon affect the body's use of:

Match each hormone with its corresponding description. -Causes muscle contraction of the uterus

Insulin:

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

What is the effect of glucagon on blood sugar level?

Adipose tissue contributes to the functioning of the endocrine system by producing a hormone called leptin, which plays a role in energy balance.

Psychosomatic relationships between human body systems and the brain have been proven not to exist.
