Flashcards in Chapter 20 Deck (35):
1

Hypothalamus

-contains neurosecretory cells that control the outpout of the anterior pituitary hormones (also known as the TROPIC hormones)

2

TSH (thyroid stimulating hormone)

Targets the thyroid gland
Thyroid stimulates metabolism

3

ACTH (adrenocorticotropic hormone)

Targets adrenal cortex
controls secretion of hormones from adrenal cortex

4

FSH (follicular stimulating hormone)

Targets the ovaries
stimulates follicle cells to secrete estrogen and stimulates production of sperm cells

5

Growth Hormone (GH)

Targets the entire body
Increases division of cells in the body

6

Prolactin (PRL)

Target memory glands
Milk production after birth

7

Anterior Pituitary

Contains endocrine cells (make other hormones)
(TSH, ACTH, FSH, GH, PRL)

8

Tropic hormones

Stimulate other endocrine organs

9

LH (luteinizing hormone)

secretion of sex hormones & releasing an egg cell in females

10

Hypothalamus controls the output of hormones in the anterior pituitary who controls the other organs in the body

11

Posterior pituitary

No cells exist here. Only hormones are dumped from the hypothalamus (ADH & OT)

12

ADH (Antidiuretic hormone)

Targets kidney tubules
Causes kidneys to conserve water in high concentration; increases blood pressures

13

Oxytocin (OT)

Targets uterine muscles & mammary glands
Contracts muscles in the uterine wall; contracts muscles with milk-seceting glands

14

Hypothalamus & Posterior pituitary Assoication

ADH & OT are made in hypothalamus and dumped in the posterior pituitary gland

15

Three things with Thyroid gland

Left & Right lobe of thyroid gland
Isthimus (middle) connects lobes

16

Follicular cells

controls TH

17

Thyroid hormone (TH)

control metabolism

18

Parafollicular cells

makes calcitonin

19

Calcitonin

regulates calcium in blood stream. calcitonin brings calcium down in the blood stream if it is too high

20

Parathyroid gland

on the backside of the thyroid gland
makes parathyroid hormone (PTH)

21

Parathyroid hormone (PTH)

when calcium levels decreases, PTH is secreted in the blood stream to increase the calcium

22

adrenal gland

located above the kidney and have two types of tissues: medulla vs cortex

23

Cortex; type of hormones

corticosteriods

24

Cortex; layers

Zona glomerulosa; mineralocorticoids (sodium)
Zona fasciaculata; glucocorticoids (glucose levels, cortisol)
Zona reticularis; gonadocorticoids (similiar to testorine &estrogen)

25

Medulla

epinepherine aka adrenaline

26

Pancreas, endocrine

Pancreatic islet (islet of Langerhans)

27

PAncreatic Islet (alpha)

makes glucagon to increase blood sugar levels by the breakdown of glycogen

28

Pancreatic islet (beta)

makes insulin
lowers blood sugar levels by the uptake of glucose

29

Testes

Testosterone: maturation of sperm, protein synths in muscles

30

Ovaries

Estrogen: maturation of eggs (follicles)
Progesterone: prepation of pregnancy

31

Stoma

produce gastrin: stimulates chief and parietel cells

32

Intestines

secretin & cholecyostokinin: slowing emptying of stomach, stimulates gallbladder contraction & pancreatic juice release

33

Kidneys

erythropoietin (EPO): stimulates red blood cell production by marrow

34

Heart

Atrial Natriuretic Peptide (ANP_): helps decrease blood pressure if gets too high

35

Pineal Gland:

Melatonin: coordinates sleep/wake cycles with daylight cycle
