the largest division of the brain
- divided into 2 hemispheres
- each one has 5 lobes

Question 2

features of cerebrum

Answer 2

1. gyri
2. sucli (central sulcus)
3. fissures (longitudinal & sylvian/lateral)

Question 3

gyri

Answer 3

elevated ridges

Question 4

sulci

Answer 4

small grooves dividing the gyri

Question 5

central sulcus

Answer 5

divides the frontal lobe from the parietal lobe

Question 6

fissures

Answer 6

deep grooves generally dividing large regions/lobes of the brain

Question 7

longitudinal fissure

Answer 7

divides the 2 cerebral hemispheres

Question 8

sylvian/lateral fissure

Answer 8

divides the temporal lobe from the frontal and parietal lobes

Question 9

Answer 9

1. frontal
2. parietal
3. temporal
4. occipital
5. insular

Question 10

frontal lobe function

Answer 10

• memory info
• emotions
• personality
• decision making/reasoning

Question 11

occipital lobe function

Answer 11

• processing, integration, and interpretation of vision and visual stimuli

Question 12

• body orientation
• sensory discrimination

Question 13

temporal lobe function

Answer 13

• perception of auditory signal
• speech comprehension
• memory

Question 14

the order of cranial nerves

Answer 14

• 1-12

Question 15

cerebrospinal fluid

Answer 15

the fluid made from the choroid plexus in each ventricle

Question 16

CSF circulation

Answer 16

1. CSF secreted by choroid plexus in each lateral ventricle
2. CSF flows through interventricular foramina into 3rd ventricle
3. choroid plexus in third ventricle adds more CSF
4. CSF flows down cerebral aqueduct to 4th ventricle
5. choroid plexus adds more CSF
6. CSF flows out 2 lateral apertures and one median aperture
7. CSF fills subarachnoid space and bathes external surfaces of brain and spinal cord
8. at arachnoid villi, CSF is reabsorbed into venous blood of dural venous sinuses
