what are 3 important sulci on the cerbral cortex

Answer 7

central sulcus
lateral sulcus
parieto - occipital sulcus

Question 8

what is the motor area of the brain ..all voluntary movements EXCEPT LOWER LIMBS are controlled from here

Answer 8

the precentral gyrus

Question 9

What happens if you damage the post central gyras

Answer 9

lose somatic sensation in lower limb

Question 10

what does the sylvian fissure divide

Answer 10

the temporal lobes

Question 11

what does the central sulcus divide

Answer 11

the frontal lobe from the parietal lobe

Question 12

the post central gyrus is destroyed will you lose movement or sensation

Answer 12

sensation

Question 13

which is area is destroyed if you are unable to perform any skillful movements

Answer 13

precentral sulcus

Question 14

what is the function of the paracentral lobule

Answer 14

movement of the lower limb

Question 15

what sulcus controls movement of the lower limb

Answer 15

paracentral lobule

Question 16

which lobe: thinking planning and motor execution

Answer 16

frontal

Question 17

which lobe : somatosensory perception

Answer 17

parietal

Question 18

which lobe : auditory function

Answer 18

temporal

Question 19

which lobe : vision

Answer 19

occipital

Question 20

if you kill the cortex you can not….

Answer 20

move or feel

Question 21

area 4 is

Answer 21

precentral gyrus (motor)

Question 22

area 3,1,2 is

Answer 22

post central gyrus (sensory)

Question 23

area 44 is

Answer 23

brocas area (speech production )

Question 24

area 17 is

Answer 24

primary visual cortex

Question 25

area 6 is

Answer 25

for skillful movements

Question 26

the majority of the superolateral surface is done by what artery?

Answer 26

Middle cerebral artery

Question 27

the majority of the medial surface of the brain is done by which artery

Answer 27

anterior cerebral artery

Question 28

which artery supplies the majority of the inferior surface of the brain

Answer 28

posterior cerebral artery

Question 29

if you block the middle cerebral artery can you walk ?

Answer 29

Yes!!! remember this will affect the motor cortex, however, it is only for the upper limbs. so you wil have face and arm hemiparesis, Broca’s aphasia , Wernicke aohaisa

Question 30

if the anterior cerebellar artery is blocked can you shave?

Answer 30

yes!! this is because it is going to supply to areas of the brain responsible for lower limb movement! . So you would have contralateral lower extremity hemiplegia and or sensory defecits

Question 31

if you block the posterior cerebral artery can you drive

Answer 31

since the posterior cerebral artery supplies the occipital lobe it will lead to homonymous hemianopia

Question 32

What separates the motor cortex from the sensory cortex

Answer 32

central SULCUS

Question 33

is the a central gyrus

Answer 33

NO!!!
