New cards
12

Hormones in posterior

ADH and oxytocin

New cards
13

ADH

Anti-diuretic hormone

New cards
14

Oxytocin

Uterus and mammary glands, milk let-down (makes still produce)

New cards
15

Hormones in Anterior

TSH, ACTH, GH, Prolactin

New cards
16

TSH (thyroid stimulating hormone)

Produce T3 and T4 (most are produced in thyroid but can be produced in anterior

New cards
17

ACTH

adrenocorticotropic hormone, adds more cortisol

New cards
18

GH

Growth hormone, promotes growth and development during childhood/adolescence

New cards
19

Prolactin

Mammary glands, stimulates milk production (anterior)

New cards
20

Hormones in pineal

Melatonin

New cards
21

Melatonin

Regulates sleep-wake cycle

New cards
22

Thyroid gland

Butterfly shaped, regulates body metabolism and storage of calcium (near neck)

New cards
23

Hormones in thyroid

Thyroxine (T4), Triiodothyronine (T3), Calcitonin

New cards
24

Thyroxine

Converted into T3

New cards
25

Triiodothyronine

Active form of T4

New cards
26

Calcitonin

Decreases calcium levels (to prevent hypercalcemia)

New cards
27

Hypercalcemia

Calcium levels are too high

New cards
28

Adrenal gland

Located near kidneys, composed of adrenal medulla and adrenal cortex

New cards
29

New cards
30

Cortisol

Stress hormone (up in glucose) (is a corticosteroid)

New cards
31

34

Epinephrine (Adrenaline)

Increases heart rate and mental alertness (corticosteroid)

New cards
35

New cards
39

Glucagon

New cards
40

Feedback mechanism

Product feeds back to control its own production, has 2 types: positive and negative

New cards
41

Positive feedback mechanism

Amplify secretion

New cards
42

Negative

Maintain hormone levels

New cards
43
