0

pet scan stands for

positron emission tomography

1

pet measures blank flow in brain

oxygen

2

fmri measures blank flow in brain

oxygen and blood

3

three parts of hindbrain

medulla oblongata, pons, cerebellum

4

three parts of brain

hindbrain, midbrain, forebrain

5

two parts of forebrain

diencephalon, cerebrum

6

two parts of diencephalon

thalamus, hypothalamus

7

four parts of cerebrum

basal ganglia, hippocampus, amygdaloid nuclei, 4 lobes

8

section of axons that connects the two halves of the brain

corpus callosum

9

motor cortex is located here

precentral gyrus

10

somatic sensory cortex is located here

postcentral gyrus

11

left brain allows one to see blank

right visual field out of BOTH eyes

12

a spoken word is received in blank, understood by blank, then blank produces speech to repeat the spoken word

auditory cortex, wernickes area, brocas area

13

reading a word out loud has words read processed in the blank, understood in blank, speech produced in blank, mouth moves because of blank

visual cortex, wernickes, brocas, motor cortex

14

transition from cell body into axon

axon hillock

15

four types of neurons

unipolar, bipolar, pseudo-unipolar, multipolar

16

three types of multipolar neurons

motor spinal cord, pyramidal cell of hippocampus, purkinje cell of cerebellum

17

three classifications of neurons

afferent, efferent, interneurons

18

three macroglia nervous system support cells

oligodendrocyte, schwann cell, astrocyte

19

microglia are just blank support cells

immune system

20

astrocytes are found in blank matter

white

21

knee jerk reflex in quad has tension sensed by blank

muscle spindle

22

exciting one motor pathway and inhibiting opposite motor pathway is an example of blank

feedforward inhibition

23

an effect that turns off an effect once activated to a certain degree

feedback inhibition

24

neurotransmitters are blank signals

electrochemical

25

short term physiological changes can change the synaptic effectiveness permanently

plasticity

26

neuronal network is plastic and can constantly blank

change
