Module 1

Question 1

glial cells

Answer 1

support and protect nerve cells: astrocytes, oligodendroglia, ependymal, microglia

Question 2

astrocytes

Answer 2

glial cells that provide shape and support

Question 3

ependymal

Answer 3

glial cells that line the ventricles of the brain and canal of spinal cord

Question 4

oligodendroglia

Answer 4

glial cells that form myelin in the CNS

Question 5

microglia

Answer 5

glial cells that are the scavenger/defense mechanism

Question 6

Schwann

Answer 6

glial cells that produce myelin in the PNS

Question 7

sagittal/median plane

Answer 7

right/left side

Question 8

frontal/coronal plane

Answer 8

front/back

Question 9

transverse plane

Answer 9

upper/lower

Question 10

gray matter

Answer 10

cell bodies

Question 11

white matter

Answer 11

myelinated axons

Question 12

lobes of brain

Answer 12

frontal, parietal, temporal, occipital, insula/limbic

Question 13

foramen magnum

Answer 13

hole in skull for brainstem

Question 14

layers of meninges

Answer 14

dura mater, arachnoid mater, pia mater

Question 15

dura mater

Answer 15

outermost, strong, attachment to spines of skull; keeps brain from sloshing around

Question 16

arachnoid mater

Answer 16

spiderweb-like; no blood vessels; CSF flows between pia mater and arachnoid mater

Question 17

pia mater

Answer 17

blood vessels; close to actual brain; CSF flows between pia mater and arachnoid mater

Question 18

ventricles

Answer 18

two lateral, then 3rd and 4th into spinal cord; CSF flows through ventricles to spinal cord and then back into subarachnoid space

Question 19

choroid plexus

Answer 19

where CSF created

Question 20

hydrocephalis

Answer 20

too much fluid in brain

Question 21

cerebrospinal fluid (CSF)

Answer 21

regulation of intracranial pressure; cleans and nourishes; shock absorber; produced in choroid plexus and reabsorbed in subarachnoid space

Question 22

cerebrum (where is gray matter?)

Answer 22

gray matter on the outside; opposite of spinal cord

Question 23

Sylvian fissure

Answer 23

lateral fissure (side)

Question 24

central sulcus

Answer 24

separates frontal and parietal

Question 25

longitudinal fissure

Answer 25

left and right

Question 26

basal ganglia

Answer 26

regulate the motor system

Question 27

diencephalon

Answer 27

thalamus, hypothalamus, epithalamus, subthalamus

Question 28

cerebellum functions

Answer 28

coordination and balance

Question 29

brainstem

Answer 29

midbrain, pons, medulla

Question 30

corona radiata

Answer 31

radiating crown (projection fibers)
