1

adrenal cortex

outer section of each adrenal gland

2

adrenal medulla

inner section of each adrenal gland

3

ovaries

located in lower abdomen of female; produces eggs, estrogen/progesterone secretion

4

pancreas

located behind stomach; islet cells secrete hormones from the pancreas

5

parathyroid glands

4 small glands on the posterior of the thyroid gland

6

pituitary gland

located at base of brain in sella turcica; composed of anterior and posterior lobes

7

testes

2 glands enclosed in the scrotal sac of a male

8

thyroid gland

located in the neck on either side of trachea

9

adrenaline (epinephrine)

secreted by adrenal medulla; increases heart rate and blood pressure, dilates airways

10

adrenocorticotropic hormone (ACTH)

secreted by anterior lobe of pituitary gland; stimulates adrenal cortex

11

aldosterone

secreted by adrenal cortex; increases salt reabsorption

12

androgen

male hormone

13

antidiuretic hormone (ADH)

increases reabsorption of water by the kidney

14

calcitonin

decreases blood calcium levels

15

cortisol

increases blood sugar

16

estradiol

estrogen secreted by the ovaries

17

estrogen

female hormone secreted by the ovaries and to a lesser extent by the adrenal cortex

18

follicle-stimulating hormone (FSH)

stimulates hormone secretion and egg production by the ovaries and sperm production by the testes

19

glucagon

increases blood sugar by conversion of glycogen to sugar

20

growth hormone (GH); somatotropin

stimulates growth of bones and soft tissue

21

insulin

helps glucose to pass into cells and it promotes the conversion of glucose to glycogen

22

luteinizing hormone (LH)

stimulates ovulation in females and testosterone secretion in males

23

norepinephrine

increases heart rate and blood pressure

24

oxytocin (OT)

stimulates contraction of the uterus during labor and childbirth

25

parathormone (PTH)

increases blood calcium

26

progesterone

prepares uterus for pregnancy

27

prolactin (PRL)

promotes milk secretion

28

somatotropin

growth hormone

29

testosterone

male hormone secreted by the testes

30

thyroid-stimulating hormone (TSH); thyrotropin

secreted by the anterior lobe of the pituitary gland; TSH acts on the thryoid gland to promote its functioning
