Answer 7

outter

outside

Question 8

where is white matter in the brain

Answer 8

inner

inside

Question 9

gray matter

Answer 9

aggregated cell bodies in CNS

1 cell body - nucleus

Question 10

accumulations of grey matter in CNS

Answer 10

nuclei

if the contained cell bodies are fxnally related to each other

Question 11

white matter

Answer 11

bundled axons

nerve fibers

Question 12

what are bundled axon coated with

Answer 12

sheath of myelin

Question 13

what is myelin

Answer 13

fatty substance

deposited around many axons as an insulating sheath

Question 14

what does the presence of myelin allow

Answer 14

nerve impulses to occur more rapidly

Question 15

myelinization

Answer 15

occurs initially in the fibers serving the primary sensory and motor fxns after birth

touches, vision, audition

Question 16

2 major division of the brain

Answer 16

hindbrain

forebrain

Question 17

hindbrain includes

Answer 17

cerebellum (balance)

pons and medulla (vital to survival)

Question 18

forebrain includes

Answer 18

cortex

amygdala

hippocampus

thalamus (relay center)

hypothalmus

Question 19

what part of the forebrain makes humans unique

Answer 19

cortex

Question 20

cerebellum

Answer 20

extremely large area

millions of neurons

Question 21

what is the cerebellum responsible for

Answer 21

coordination of movement

plays a role in learning

Question 22

pons

Answer 22

important for sleep and dreaming

Question 23

medulla

Answer 23

controls all vital fxns of the body including breathing and HR

Question 24

thalamus

Answer 24

primary relay center of the brain

almost all sensory info passes through before going elsewhere

Question 25

hypothalmus

Answer 25

regulates ANS

regulates hormones –> feeding, fighting, fleeing and sexual behavior

Question 26

amygdala

Answer 26

responsible for many aspects of emotion

emotional learning

Question 27

hippocampus

Answer 27

esp important for learning and memory

resolving conflict

Question 28

cerebral cortex is primarily what matter

Answer 28

gray

Question 29

what is deep w/in the cerebral cortex

Answer 29

groups of cell bodies

basal ganglia in the cerebrum

white matter connects the areas of gray matter

Question 30

neocortex –> cerebral cortex

Answer 30

portion of the cortex that has evolved dramatically during evolution

only found in mammals

connector tissues

Question 31

what does the cerebral cortex do

Answer 31

just about everything

many think the cortex is what makes humans the way they are

Question 32

4 parts of the cortex

Answer 32

frontal lobe (front of the brain)

temporal lobe (side, the temples)

parietal lobe (middle portion)

occipital lobe (very back)

Question 33

occipital lobe

Answer 33

concerned w/ many aspects of vision

Question 34

where is the frontal lobe

Answer 34

front of the central sulcus

Question 35

what does the frontal lobe do

Answer 35

concerned w/ reasoning, planning, parts of speech and movement, emotions and problem solving

Question 36

what lobe do stroke really affect

Answer 36

frontal lobe

Question 37

where is the temporal lobe

Answer 37

below the lateral fissure

Question 38

what does the temporal lobe do

Answer 38

perception and recognition of auditory stimuli and memory

(hippocampus)

Question 39

where is the parietal lobe

Answer 39

behind the central sulcus

Question 40

what does the parietal lobe do

Answer 40

perception of stimuli related to touch, pressure, temp and pain
