Communication

Question 1

nervous system

Answer 1

regulation of body functions

rapid, short acting effects

Question 2

Endocryn system

Answer 2

regulation of body function
Acts slowly with long lasting effects

Glands secrete hormones into the blood -Travels to target organ, - Regulates activity

Question 3

glands

Answer 3

parts of the body that makes a message and sends it to another part of the body

Question 4

stereroid hormones

Answer 4

Made from cholesterol
Pass through cell membrane of target cell

Question 5

non stereroid hormones

Answer 5

 Made from proteins
 Attach to receptor outside of cell to send message into cell

Question 6

dopamine

Answer 6

Regulates movements, attention, learning, and emotional responses (desire/pleasure/satisfaction) - “Reward System”

Question 7

Seratonin

Answer 7

mood stabalizer, arousal/happiness, digestive system, nausea, sexual function

Question 8

Epinephrine / norepinephrine / adrenaline

Answer 8

Fight/Flight, arousal, exhilaration, changes size of blood vessels

Question 9

Cortisol

Answer 9

Stress hormone, helps wih metabolism, anti-inflammatory, regulates blood pressure

Question 10

SSRI

Answer 10

Selective Seratonin Reuptake inhibutor

Question 11

Hypothalamus in reference to nervous systems

Answer 11

master gland of body regulation

controls nervous and endocryn system

Can detect levels of hormones and can send messages to the pituitary gland which sends messages to organs

Question 12

negative feedback loop

Answer 12

homeostasis - balance

most of body works on

A-B-C

Hypothalamus → pituitary → end organ

if not enough of C body makes A start producing more

If enough of C then A shuts off

Question 13

Positive Feedback loop

Answer 13

A-B-C

Hypothalamus → pituitary → end organ

A never shuts off so exponential growth of C

Question 14

2 functions of body that perform positive feedback loop

Answer 14

ovulation and birth

Question 15

Sexual Feedback

Answer 15

Question 16

1. secrete testosterone
2. make sperm

Function: “Promotes maturation of gonads, regulates menstrual cycle” (2013, p. 82).

“Stimulates pituitary during sperm production” (2013, p. 114).

Question 23

Estrogen

Answer 23

Origin: Ovaries, adrenal glands, placenta (during pregnancy)

Question 24

Testosterone

Answer 24

Origin: Adrenal glands, ovaries, testes

Function: “Helps stimulate sexual desire” (2013, p. 82).

Answer 26

Origin: Hypothalamus, testes

Function: “Stimulates uterine contractions during childbirth and possibly during orgasm, promotes milk let-down” (2013, p. 82).
