Ets Exam, Set #1

Front 1

brain stem

Back 1

control of physiological functions and automatic behaviors

Front 2

cerebellum

Back 2

control and coordinate movements, like rapid skilled movements

Front 3

cerebral hemispheres

Back 3

involved in perceptions, memories, behaviors

Front 4

cerebral cortex

Back 4

thin top layer of brain, often called gray matter

Front 5

glial cells

Back 5

hold system of neurons together

Front 6

ions

Back 6

particles produced with various substances are dissolved into water.

Front 7

MRI
(magnetic resonance imaging)

Back 7

place head in strong magnetic field and then place radio signal within and sense molecules of brain

produce higher res images than CT scanners, but more expensive and cannot come into contact with pace makers, etc.

Front 8

CT, or CAT scanner

Back 8

computerized tomography

takes an image of a slice of the brain, sends x rays through person's head

Front 9

PET scan

Back 9

positron emission tomography
give person an injection of a radioactive chemical that accumulates in the brain, head placed into the scanner, then detects the positrons

Front 10

functional MRI

Back 10

fMRI, preferred method of measuring activity of human brain, like MRI but takes a lot less time

Front 11

primary visual cortex

Back 11

receives visual information, located in back of the brain

Front 12

primary auditory cortex

Back 12

receives auditory information, side of the brain

Front 13

primary somatosensory cortex

Back 13

vertical strip near middle of the cerebral hemispheres on the parietal lobe, receives information from the body senses

Front 14

thalamus

Back 14

located in the breat of cerebral hemispheres, divided into two parts

receives sensory information, all sensory information, except for olfaction, is sent to thalamus before sent to cerebral cortex

Front 15

corpus callosum

Back 15

"band" that connects the two hemispheres of the brain

connects left and right parts of brain - left and right parietal lobes,

Front 16

frontal lobes

Back 16

motor activity, planning strategies for action, wvaluating them, and changing them if necessary

Front 17

cerebellum

Back 17

control of movement, fluid movement of rapid, skilled movement

Front 18

basal ganglia

Back 18

group of neurons deep in the cerebral hemispheres, next to the thalamus

control of movements, particularly slow ones than involve large mucles of the body

Front 19

limbic system

Back 19

contains the hippocampus and amygdala

hippocampus, involved in episodic memory or learning and remembering experiences from daily lives, and learning how to do things

amygdala - emotional behavior, esp. negative emotions caused by stressful events

Front 20

hypothalamus

Back 20

below thalamus, participates in homeostasis and species-typical behaviors
