Answer 5

isthmus

Question 6

Answer 7

medial surface of the temporal lobe

Question 8

what is the other term for calcarine gyrus?

Answer 8

striate cortex

Question 9

where is the gustatory (taste) cortex located?

Answer 9

Inferior post central gyrus

Question 10

Where does the lateral ventropostral nucleus receive information from?

Answer 10

leg

Question 11

where does the medial ventropostral nucleus recieve information from?

Answer 11

arm

Question 12

where is the general sensory area located

Answer 12

superior parietal lobe

Question 13

what is the function of secondary areas?

Answer 13

they are the association areas that provide understanding to sensory input.

Question 14

what does equipotential mean /

Answer 14

the sensory and motor association areas function the same amount

Question 15

Agnosia

Answer 15

Agnosia is when awareness persists but there is no understanding of the sensation.
It occurs when the secondary sensory areas are damaged.

Question 16

What is Apraxia?

Answer 16

Apraxia is the inability to perform purpose movements. It is caused by damage to secondary motor areas.

Question 17

What is the general association cortex?

Answer 17

it has an integrative function. It links together all the senses and the hippocampus.

• The parieto-temporal cortex is involved in memory.
• The Prefrontal cortex is involved in regulating moods and feelings. It allows decisions to be made by analysing previous experiences.

Question 18

Language areas of the brain

Answer 18

2 language areas are in the Dominant hemisphere.

1) posterior area (wernicke’s area) is for understanding
2) Anterior area (Broca’s area) is for production of language.

Question 19

what is aphasia?

Answer 19

damage to wernicke’s area causes inability to understand language.
damage to broca’s area causes inability to articulate speech.
