1

What is the second major control system of the body

Endocrine system

2

What is the difference between the endocrine system and nervous system?

Endocrine system uses chemical impulses, hormones

3

arouses the body tissue and cells by stimulating changes in their metabolic activity. This includes growth, development, and physiological homeostasis

Hormones

4

can be steriods or amino acid based molecules

hormones

5

How does a hormone travel?

Through the blood

6

Cells within an organ that respond to a certain hormone

Target cells

7

Two functional lobes of the pituitary

adenohypophysis and neurohypophysis

8

anterior pituitary

adenohypophysis

9

stalk attaching the pituitary to the hypothalamus

neurohypophhysis

10

Which part of the pituitary secretes the 4 tropic hormones?

Anterior pituitary

11

Hormones that have other endocrine glands as their target

Tropic hormones

12

Is the posterior pituitary an endocrine gland?

No

13

Why is the posterior pituitary not considered an endocrine gland?

1. It does not synthesize the hormones it releases. 2. it acts as a storage area for two neurohormones transpported to it

14

What are the tropic hormones of the pituitary gland?

1. Thyroid stimulating hormone (tsh). 2. follicle stimulating hormone ( FSH). 3. Luetenizing hormone (LH) 4. Adrenocorticotropic hormone (ACTH)

15

TSH target gland

Thyroid gland

16

TSH effects

Stimulation of thyroid hormones

17

Target of follicle stimulating hormone

Ovaries and testes

18

Effects of FSH

Ovaries- stimulates ovarian follicle maturation and estrogen production. Testes- Stimulates sperm production

19

Target cell of LH

Ovaries and testes

20

Effects of LH

Stimulates ovulation and triggers ovarian production of estrogen and progesterone. Males- Stimulates testosterone production

21

Target of ACTH

Adreneal cortex

22

Effects of ACTH

Stimulates the release of glucocorticoids and androgens

23

Non tropic hormones of the anterior pituitary gland

Growth hormone (GH) and Prolactin (PRL)

24

Target organs of growth hormone

liver, muscle bone, and cartilage

25

Effects of growth hormone

Stimulates body growth and protein synthesis. mobilizes fat and conserves glucose.

26

Target organs of prolactin

Mammary glands of breast

27

Effects of prolactin

Stimulates milk production

28

Hormones stored by posterior pituitary gland

oxcytocin and antidiarectic hormone

29

Target of antidiretic hormone

kidney

30

Target of ocytocin

Uterus, mammary glands
