Flashcards in Topics 18-20: Endocrine, Reproductive, and Nervous Systems Deck (32):
1

growth factors and prostaglandins are what kind of regulators?

Paracrine regulators

2

cytokines are what kind of regulators?

autocrine regulators

3

modified tyrosine produced by thyroid gland, increases metabolic rate

thyroxine

4

controlled by hypothalamus

made up of 2 parts

Pituitary gland

5

hormones made in hypothalamus, secreted by this pituitary gland

Posterior pituitary

6

Gland that makes ADH and oxytocin

Posterior pituitary

7

Gland that makes its own hormones, many stimulate growth

Anterior pituitary

8

Gland that makes ACTH, TSH, LH, FSH, etc.

Anterior pituitary

9

stimulates production of corticosteroids in adrenal cortex

ACTH

10

stimulates production of thyroxine in thyroid

TSH

11

testosterone production, ovulation, and corpus luteum formation

LH

12

needed for spermatogenesis and development of ovarian follicles

FSH

13

What makes thyroxine and calcitonin?

Thyroid

14

2 essential hormones

PTH and aldosterone

15

What makes PTH?

parathyroid

16

Increases blood Ca++ level, reabsorb Ca++ in kidneys, absorb Ca++ from food in intestine

PTH

17

Part of adrenal glands for mineral and glucose balance

Adrenal cortex (outer)

18

Part of adrenal glands for "fight or flight"

Adrenal medulla (inner)

19

reabsorbs Na+ for normal blood volume

aldosterone

20

What's it called when an individual can change its sex (most common in fish)

Sequential hermaphroditism

21

period of sexually receptivity (these females have an estrous cycle)

estrus

22

Oogenesis cycle parts:

Follicular phase, ovulation, luteal phase

23

What part of the cycle has an increase in estradiol causeing an LH spike

ovulation

24

after ovulation, empty Graafian follicle becomes corpus luteum, which makes estradiol/progesterone to inhibit production of FSH and LH

luteal phase

25

mimics LH, keeping corpus luteum alive and preventing menstruation

hCG

26

What does a sodium-potassium pump bring out and bring in?

Pumps out 3 Na+, pumps in 2 K+

27

What happens in an action potential:

1.) Na+ channels open, Na rushes inside

2.) Rapid change in membrane potential

3.) K+ channels open, K+ rushes inside

4.) Rapid repolarization

28

gaps every 1-2 mm, letting action potentials to travel faster along myelinated axons

nodes of Ranvier

29

integrates brain with spinal cord; controls breathing

medulla oblongata (brain stem)

30

involved in coordination and motion memory; associated with medulla oblongata

cerebellum

31

motor control, memory, emotion, higher functions (in cerebral cortex)

cerebrum

32

integrates the hemispheres of the cerebrum

corpus callosum
