Psychology Chapter 2

Front 1

describe function of the endocrine system

Back 1

regulates and manages everything from physical growth to stree response

Front 2

Pituitary gland

Back 2

master gland; regulates other endocrine glands; releases horomones

Front 3

Thyroid Gland

Back 3

produces thyroxine; a disorder affects metabolism (weight gain)

Front 4

horomone

Back 4

stir up; excite

Front 5

Adrenal Glands accomplish...

Back 5

produces epinephrine

Front 6

two subsystems of nervous system

Back 6

PNS and CNS

Front 7

PNS

Back 7

carries messages to and from CNS

Front 8

CNS

Back 8

main processesing system of information

Front 9

parts of PNS

Back 9

somatic, autonomic

Front 10

parts of CNS

Back 10

brain and spinal cord

Front 11

afferent neurons

Back 11

sends messages to the brain

Front 12

efferent neurons

Back 12

messages from brain to spinal cord

Front 13

neuron

Back 13

single cell and the building block of the nervous system

Front 14

parts of a neuron

Back 14

soma, dendrites, axon

Front 15

function of dendrites

Back 15

receive signals and carry them to cell body, sends them to axon

Front 16

3 characteristics of neurons

Back 16

dont grow back; damage is permanent; threshold of excitation

Front 17

threshold of excitation

Back 17

neurons fire when dendrites are stimulated; then depolarized; positively charged particles pushed outside neuron; neuron returns to its initial resting state

Front 18

action potential of neurons

Back 18

neuron is depolarized: neuron is stimulated or resting state is disturbed

Front 19

neurotransmitters

Back 19

chemical substance in axon

Front 20

types of neurotransmitters

Back 20

Acetycholine; Norepinephrine; Seratonin; Endorphins; Dopamine

Front 21

somatic nervous system

Back 21

respons to external senses (sight, taste, hearing..)

Front 22

autonomic nervous system

Back 22

controls vital and automatic activities (heart rate, blood pressure, internal organs)

Front 23

importance of somatic

Back 23

processes information; carries info from sense organs to the brain (what causes us to see an car coming and move)

Front 24

parasympathetic nervous system

Back 24

calms things down, moves heartbeat to normal after emergency

Front 25

3 parts of the brain

Back 25

hindbrain, midbrain, forebrain

Front 26

hindbrain

Back 26

holds the cerebellum, medulla, the pons; interprets signals and cause the body to immediately act

Front 27

forebrain

Back 27

largest, most complicated part of the brain

Front 28

higher thinking process

Back 28

takes place in forebrain;

Front 29

thalamus

Back 29

sensory information

Front 30

function of dendrites

Back 30

receive signals and carry them to cell body, sends them to axon

Front 31

3 characteristics of neurons

Back 31

dont grow back; damage is permanent; threshold of excitation

Front 32

threshold of excitation

Back 32

neurons fire when dendrites are stimulated; then depolarized; positively charged particles pushed outside neuron; neuron returns to its initial resting state

Front 33

action potential of neurons

Back 33

neuron is depolarized: neuron is stimulated or resting state is disturbed

Front 34

Back 34

Front 35

Back 35

Acetycholine; Norepinephrine; Seratonin; Endorphins; Dopamine

Front 40

3 parts of the brain

Back 40

hindbrain, midbrain, forebrain

Front 41

hindbrain

Back 41

holds the cerebellum, medulla, the pons; interprets signals and cause the body to immediately act

Front 42

forebrain

Back 42

largest, most complicated part of the brain

Front 43

higher thinking process

Back 43

takes place in forebrain;

Front 44

thalamus

Back 44

sensory information

Front 45

hypothalamus

Back 45

motivation, emotion; regulates body temp

Front 46

RAS

Back 46

Reticulating Activating System

Front 47

Limbic System (parts)

Back 47

Thalamus; Hypothalamusl; Amygdala; Hippocampus

Front 48

Pancreas

Back 48

produces insulin and glucogen; controls sugar metabolism

Front 49

Thymus Gland

Back 49

behind breastbone; important to immune system

Front 50

Testes

Back 50

produce sperm and testosterone

Front 51

Ovaries

Back 51

produce estrogen and progesterone
