Brain Parts

Question 1

PET

Answer 1

radioactive glucose injection

computer detects which cells use glucose, detects activity of brain cells

Question 2

MRI

Answer 2

machine with magnetic field that aligns hydrogen atoms in brain tissues then radio pulses used to make atoms spin, time for atoms to return to normal spin allows computer to make 3-d image
better spatial resolution

Question 3

CT scan

Answer 3

series of x rays of brain with computer help, good for imaging brain structure
strokes, tumors, etc, method of choice when there is metal in the body
useful for imaging possible skull fractures

Question 4

medulla

Answer 4

part of hindbrain

controls heartbeat, breathing, and swallowing

Question 5

pons

Answer 5

coordinate left and right side movements
influences sleep, dreaming, and arousal
hindbrain
relays messages between cerebellum and cortex

Question 6

reticular formation

Answer 6

hindbrain
allows people to ignore constant, unchanging information and become alert to changes in information
controls arousal and attention

Question 7

cerebellum

Answer 7

controls all involuntary, rapid, fine motor movement
controls balance and maintains muscle coordination
hindbrain
coordinates rapid voluntary movements
learned reflexes and skills

Question 8

hindbrain

Answer 8

medulla pons reticular formation cerebellum

Question 9

limbic system

Answer 9

thalamus hypothalamus hippocampus amygdala cingulate cortex

Question 10

thalamus

Answer 10

relay station for incoming sensory information
limbic system
processes sensory information
smell is only sense that doesn’t have to pass through thalamus first
relays information from sensory organs to cerebral cortex

Question 11

hypothalamus

Answer 11

regulates body temperature, thirst, hunger, sleeping and waking, sexual activity, and emotions
controls pituitary gland
regulation of hormones
limbic system

Question 12

hippocampus

Answer 12

limbic system
forming long term memories
ACh
role in learning, memory, and ability to compare sensory information to expectations

Question 13

amygdala

Answer 13

fear responses and memory of fear
limbic system
information for senses goes to amygdala before other parts of brain
influences motivation, emotional control, fear response, and interpretations of nonverbal emotional expressions

Question 14

cingulate cortex

Answer 14

limbic system
emotional and cognitive processing
memory, attention

Question 15

cerebral hemispheres

Answer 15

cortex divided into these two sections

Question 16

corpus callosum

Answer 16

allows left and right hemispheres to communicate

connects the hemispheres

Question 17

occipital lobes

Answer 17

processes visual information from eyes
primary visual cortex processes the information
visual association cortex helps identify and make sense of the information

Question 18

parietal lobes

Answer 18

contain somatosensory cortex
processes information from skin and internal body receptors for touch, temperature, and body position
spatial awareness

Question 19

temporal lobes

Answer 19

contain primary auditory cortex and auditory association area
language area, learning and memory, visual information

Question 20

frontal lobes

Answer 20

higher mental functions of brain—planning, personality, memory storage, complex decision making, language
helps control emotions

Question 21

motor cortex

Answer 21

in frontal lobes

control movements of body’s voluntary muscles by sending commands to somatic division of peripheral nervous system

Question 22

cerebrum

Answer 22

upper part of brain consisting of the two hemispheres and the structures connecting them

Question 23

left hemisphere

Answer 23

controls right hand
spoken and written language
math and logical thought
analysis of detail
reading

Question 24

right hemisphere

Answer 24

controls left hand
nonverbal
visual spatial perception
music and art
emotional thought and recognition
processes whole
pattern and facial recognition
