yeah 1

Question 1

biological psychology

Answer 1

the scientific study of the biological bases of behavior and mental processes

Question 2

neurons

Answer 2

basic cells of the nervous system, communicates throughout nervous system.

cells that are highly specialized to receive and transmit information from one part of your body to another

Question 3

Sensory neuron

Answer 3

conveys information about the enviorment, such as light or sound

carries info from skin and internal organs to brain

Question 4

motor neuron

Answer 4

communicates to muscles and glands

Question 5

basic components of neurons

Answer 5

cell body, dendrites, and axon

Question 6

interneuron

Answer 6

communicates information between neurons (most neurons are interneurons, many connect)

Question 7

cell body

Answer 7

processes nutrients, providing the energy needed to function (called soma)

Question 8

Where is the neculus?

Answer 8

Cell body, containing the DNA (chromosomes)

Question 9

dendrites

Answer 9

the part of the neuron that receives messages from other neurons, short branching fibers

the more branches they have, the more info they recieve

Question 10

axon

Answer 10

carries information to other parts of the body. neurons, muscles or glands

single long tube that extends from cell body into most neurons. neurons only have 1 axon

Question 11

glaial cells

Answer 11

cells that provide the structural and functional support for neurons throughout the nervous system. alot in the brain, take up 50%

Question 12

oligoden

Answer 12

form myelin sheath, a white and fatty, covering some axons

insaltes, and makes faster

Question 13

microgali

Answer 13

clean up work. break down and removed damaged and dead

a lot of this in brain is sign of infection, stroke, or trauma

Question 14

arstrocratos

Answer 14

most common. structural support, provide nutrient, help keep healthy. keeps toxic shit away. capable of dividing

Question 15

neurons only become active when stimulated by another source

Answer 15

just know this

Question 16

stimulus threshold

Answer 16

the minimum level of stimulation required to activate a particular neuron

Question 17

action potential

Answer 17

when stimulus threshold is reached, dendtries send signals to body (soma). Soma creates breif electrical pulse that transmits info along the axon

Question 18

resting potetinal

Answer 18

waiting to be activated, -70 millivolts

Question 19

polarized

Answer 19

negative inside, positive outside

Question 20

synapse

Answer 20

point of communication between neurons

Question 21

pre sypantic neuron

Answer 21

message sending neuron

Question 22

post sympantic neuron

Answer 22

message receiving

Question 23

acetylcholine

Answer 23

communicates to muscles, blinking, breathing, movement

Question 24

nervous system

Answer 24

system of linked neurons throughout the body that communicate.

Question 25

what are two nervous system parts

Answer 25

central and peripheral

Question 26

nerves

Answer 26

large bundles of neurons carrying info in peripheral system

Question 27

central nervous system

Answer 27

brain and spinal chord. every action, thought, feeling and sensation

Question 28

spinal chord

Answer 28

handles incoming and outgoing messages

Question 29

peripheral nervous system two parts

Answer 29

somatic automatic

Question 30

somatic

Answer 30

receives info and sends it to central nervous system

Question 31

automatic

Answer 31

involuntary functions, heart beat, breathing

Question 32

what nervous system alerts the body of danger?

Answer 32

Sympatheic nervous system

Question 33

what system calms you down after emergency?

Answer 33

parasympethic

Question 34

endocrine system

Answer 34

produces hormones throughout body

Question 35

forebrain

Answer 35

uppermost and largest brain region most complex

Question 36

hindbrain

Answer 36

connects brain to spinal cord medulla, pons, and cerebellum

Question 37

midbrain

Answer 37

processes visual and auditory

Question 38

hippocampus

Answer 38

ability to form new memories

Question 39

thalamus

Answer 39

sensory expect smell

Question 40

hypothamuals
