Chapter 11-Nervous System 2

Question 1

tentorium cerebelli

Answer 1

separates occipital lobe of cerebrum from cerebellum

Question 2

falx cerebri

Answer 2

separates right and left cerebral hemispheres; extends toward longitudinal fissures

Question 3

falx cerebelli

Answer 3

separates right and left cerebellar hemispheres

Question 4

function, location and formation of cerebrospinal fluid

Answer 4

function: protects brain from damage and helps maintain stable ionic concentration
formation: choroid plexuses secrete CSF
location: choroid plexuses between pia mater and subarachnoid, CSF goes through ventricle accumulates in subarachnoid

Question 5

hemispheres

Answer 5

falx cerebri: separates

left: usually dominant-analytical
right: non-dominant-patterns

Question 6

corpus callosum

Answer 6

connects both hemispheres

Question 7

convolutions

Answer 7

ridge

Question 8

sulci

Answer 8

shallow to somewhat deep groove

Question 9

gyri

Answer 9

top of canyon

Question 10

fissures

Answer 10

separates hemispheres

Question 11

lobes

Answer 11

frontal: front
parietal: top middle
occipital: back
temporal: by ears

Question 12

cerebral cortex

Answer 12

thin layer of gray matter covers cerebrum

allows higher brain function

Question 13

sensory areas

Answer 13

parietal: touch taste temp pain
occipital: vision
temporal: smell and emotion, hearing and patterns

Question 14

association areas

Answer 14

occipital: recognizing faces
frontal: concentration and analysis
parietal: expressing emotion, understanding and speaking
temporal: stores memories, patterns, categories rhythm

Question 15

motor areas

Answer 15

primary motor areas: controls skeletal muscles
brocas: speech only
frontal eye field: controls eye muscle

Question 16

thalmus

Answer 16

recieves sensory info and branches it off into specific part of brain

Question 17

hypothalmus

Answer 17

regulates body temperature

releases hormones

Question 18

infindibulum

Answer 18

connects hypothalmus and pituitary gland

Question 19

posterior pituitary gland

Answer 19

responds to neural signals

Question 20

pineal gland

Answer 20

body rhythm melatonin

Question 21

limbic system

Answer 21

emotions odors

Question 22

midbrain

Answer 22

turn when you hear see smell

Question 23

pons

Answer 23

control respiratory in between medulla oblongata and midbrain

Question 24

medulla oblongata

Answer 24

conducts ascending and descending

vital and non vital reflexes

Question 25

reticular formation

Answer 25

sleep, chooses important impulses

Question 26

basal nuclei ganglia

Answer 26

produces dopamine relay station for motor impulses

Parkinsons: bn degenerates, dopamine stops = tremors

Question 27

long term memory

Answer 27

creates new synapes

or repeated stimulation

Question 28

anatomy of cerebellum

Answer 28

primarily white matter

cerebellar cortex: grey matter covers cerebellum

Question 29

peduncle

Answer 29

moves body to desired position

inferior: where it is
middle: where it wants to go
superior: sends correcting impulse

Question 30

physiology of cerebellum

Answer 30

balance
