What are the nine glands that produce hormones?

Adrenal
islets of langerhans (prancreas)
parathyroid.
Pineal
pituitary
hypothalamus
thymus
thyroid
gonads (ovaries and testes)

2

What is homeostasis?

An organisms maintenance of a relatively stable internal environment.

3

What is insulin?

Pancreatic hormone that regulates the use and storgae of glucose by cells; decreases blood glucose.

4

What is glucagon?

Pancreatic hormone that initiates the breakdown of glycogen to glucose, which raises blood glucose levels.

5

What is parathormone?

Parathyroid hormone that regulates calcium and phosphate ions in the blood.

6

What is Andrenocorticotropic Hormone? (ACTH)?

Anterior pituitary hormone that stimulates the adrenal cortext to produce and secrete its hormones.

7

What is Gastrin?

Stomach hormone that stimulates gastric glands to secrete gastric juices.

8

What is secretin?

Small intestine hormone that stimulates the pancreas to secrete pancreatic juice.

9

What is thyroxin?

Hormone produced by the thyroid. Regulates the rate of cell metabolism.

10

What is adrenalin?

Adrenal medulla hormone that stimulates heartbeat, breathing and blood pressure. Also called ephinephrine.

11

What is Cortisone?

Glucocorticoid hormone secreted by the adrenal cortex.

12

What is growth hormone?

Anterior pituitary hormone that promotes growth.

13

What is prolactin?

Anterior pituitary hormone that stimulates production of milk during and after pregnancy.

14

What is TSH (thyroid stimulating hormone)

Anterior pituitary hormone that stimulates the thyroid gland to produce and release thyroxin.

15

What is Oxytocin?

Posterior pituitary hormone that stimulates uterine contraction and relase of milk from the mammary glands.

16

What is testosterone?

Steroid hormone produced in the testes, of the male; regulates male secondary sexual traits and sperm production.

17

What is estrogen?

Steroid hormone produced in the ovaries of the female; regulates secondary female sexual traits and the menstrual cycle.

18

What is Antidiuretic hormone?

Posterior pituitary hormone that regulates the rate of water absorption in the kidneys and intestines. Also called vasopressin.
