brain quiz

Question 1

medulla

Answer 1

regulates breathing, cardiac centre (heart rate & force), vasometer centre (blood pressure), RAS

Question 2

pons

Answer 2

regulates breathing (along with medulla), contains centres for hearing and balance

Question 3

cerebellum

Answer 3

subconscious control of all movements, maintains balance, posture

Question 4

midbrain

Answer 4

reflexes for eye & ear, area of dopamine synthesis, part of motor pathway working with basal nuclei

Question 5

thalamus

Answer 5

gateway to cerebral cortex, edits sensory information, provides crude awareness

Question 6

hypothalamus

Answer 6

controls ANS, regulates part of endocrine system, synthesis of hormones, responsible for drives, controls body temperature, part of RAS and limbic system

Question 7

pineal gland

Answer 7

influenced by light, secretes melatonin

Question 8

pituitary gland

Answer 8

master endocrine gland of the body, secretes tropic hormones (control activites of other endocrine glands)

Question 9

limbic system

Answer 9

emotions, pain, pleasure

Question 10

RAS (reticular activation system)

Answer 10

determines state of alertness and focus

Question 11

basal nuclei

Answer 11

masses of grey matter deep within each hemisphere; help in unconscious control of voluntary movements

Question 12

corpus callosum

Answer 12

large commissure connecting hemispheres of the brain, allows communication between right brain and left brain

Question 13

fornix

Answer 13

tract that connects parts of the limbic system and forms the floor of the lateral ventricles

Question 14

frontal lobe

Answer 14

thinking, voluntary motor control

Question 15

parietal lobe

Answer 15

somatosensory (touch, pressure, temperature)

Question 16

temporal lobe

Answer 16

hearing

Question 17

occipital lobe

Answer 17

vision

Question 18

spinal cord

Answer 18

skeletal muscle reflexes

Question 19

primary somatosensory

Answer 19

precisely localizes light, touch & pressure stimuli

Question 20

primary visual

Answer 20

receives visual info from the eyes

Question 21

primary auditory

Answer 21

receives auditory info from the ears

Question 22

primary motor

Answer 22

located in pre-frontal gyrus, controls individual skeletal muscles, devoted to control of precise muscles in face and hands

Question 23

frontal eye field

Answer 23

controls movement of the eyes

Question 24

broca’s

Answer 24

controls muscles in larynx and tongue that produce speech

Question 25

motor association

Answer 25

controls patterns of skeletal muscle movements

Question 26

wernicke’s

Answer 26

interprets speech, found in GIA

Question 27

general interpretative area

Answer 27

between temporal, parietal and occipital lobes; correlates information from sensory areas

Question 28

prefrontal cortex

Answer 28

abstract thought & consequences of actions

Question 29

auditory association

Answer 29

interprets sounds

Question 30

visual association

Answer 30

interprets vision

Question 31

somatosensory association

Answer 31

deeper interpretation of stimuli received by primary sensory area

Question 32

left hemisphere

Answer 32

logical, sequential processing of information (ex: math, planning)

Question 33

right hemisphere

Answer 33

hollistic, “big picture” processing of information (ex: recognizing faces, interpreting body language)
