1

The endocrine system assist the nervous system in homeostasis and plays important role in

growth and sexual maturation

2

the two systems endocrine and nervous meet at the

hypothalamus and pituitary gland

3

What governs the pituitary?

hypothalamus
Controlled by the feedback of hormones in the body

4

Which system has a longer-lasting widespread effect in the body

endocrine

5

are chemical messengers that control the growth, differentiation, and metabolism of specific target cells

hormones

6

Two major groups of hormones are

steroid and non steroid

7

Steroid hormones

enter target cells and have a DIRECT effect on the DNA of the nucleus

8

Nonsteroid hormones are

protein hormones

9

Many protein hormones remain at the cell surface and act through a second messenger, usually a substance called

adenosine monosphate (AMP)

10

Most hormones affect cell activity by

altering the rate of protein synthesis

11

What is the main function of each gland?

to produce hormones

12

What are the other organs that also produce hormones?

stomach, small intestine, and kidneys

13

Cortisol

released from the adrenal cortex
reduces inflammation, raise blood sugar, and inhibit the release of histamine

14

Pituitary gland

mater gland
connected to the hypothalamus by the infundibulum
anterior lobe (adenohypophysis) and posterior lobe (neurohypophysis)

15

Hormones of the adenohypophysis are called

tropic hormones, because they act mainly on other endocrine glands

16

The tropic hormones include:

Growth hormone (GH)
Adrenocorticotropic hormone (ACTH)
Thyroid stimulating hormone (TSH)
Follicle-stimulating hormone (FSH)
Lutenizing hormone (LH)

17

Hormones released from the posterior lobe include

oxytocin (labor hormone)
antidiuretic hormone (ADH)

18

Other important endocrine glands include

thyroid
parathyroid
adrenals
pancreas
gonads
