corpus callosam

Question 7

what is the gyri and sulci of the neural cortex?

Answer 7

gyri - elevations on the surface of the cerebrum

sulci- depressions on the surface of the cerebrum

Question 8

function of gyri and sulci of neural cortex ?

function of the temporal lobe

Answer 11

primary auditory, smell and speech area

Question 12

function of the parietal lobe

processing centres- perform ___________________

Answer 16

higher-level analytical functions including Wernicke’s and Broca’s area both involved in speech

Question 17

what is contralateral control?

Answer 17

the major cortex of each cerebral hemisphere is mainly responsible for control of movement of the opposite side of the body

right side of the brain- left side of the body

left side of the brain- right side of the body

Question 18

processing centres are integrative areas, usually in ______________

Answer 18

dominant hemisphere (left)

Question 19

Wernicke’s area is also known as the

Answer 19

general interpretive area

Question 20

the function of Wernicke’s area?

Answer 20

it integrates sensory information to form visual and auditory memory

Question 21

the speech center is also known as the ____?

Answer 21

broca’s area

Question 22

the function of Broca’s area

Answer 22

regulates breathing and vocalization, the motor skill needed for speaking

Question 23

stroke is also known as

Answer 23

cerebrovascular accident

Question 24

what is cerebrovascular accident

Answer 24

it is also known as stroke which is a sudden death of brain cells and tissues

Question 25

how stoke/ cerebrovascular accident (CVA) arises

Answer 25

due to the lack of oxygen when the blood flow to the brain is lost by blockage (ischemic) or rupture of an artery to the brain (hemorrhagic)

Question 26

what is aphasia

Answer 26

language disorder that affects the ability to communicate aphasia does not impair the person's intelligence

Question 27

aphasia is common in

Answer 27

dominant hemisphere stroke (left)

Question 28

what is Wernicke's aphasia?

Answer 28

ability to grasp the meaning of spoken words is chiefly impaired. it is commonly associated with dominant temporal lobe CVA

Question 29

What is Broca's aphasia

Answer 29

individual with broca's aphasia have trouble speaking fluently but their comprehension can be relatively preserved. It is associated with frontal lobe/ motor disorders

Question 30

diencephalon includes

Answer 30

hypothalamus, thalamus, and pineal gland

Question 31

what is the function of hypothalamus?

Answer 31

regulates hunger, sleep, thirst , body temperature and water balance controls the pituitary glands; serves as a link between the nervous and endocrine system

Question 32

the function of the thalamus

Answer 32

receives all sensory input except the sense of smell and sends it to the the appropriate areas of the cerebrum

Question 33

function of the cerebellum?

Answer 33

receives and integrate sensory input from the eyes, ears and muscles about the current position of the body- adjusts postural muscles to maintain balance.

Question 34

function of the midbrain?

Answer 34

relay station between the cerebrum and the spinal cord or cerebellum has reflex centers for visual, auditory and tactile

Question 35

function of the pons?

Answer 35

communicates between the cerebellum and the rest of the CNS

Question 36

medulla oblongata contain __________________

Answer 36
