Answer 8

Both

Question 9

Answer 9

Both

Question 10

Answer 10

Both

Question 11

Broca’s area hemisphere

Answer 11

Left

Question 12

Wernickes area hemisphere

Answer 12

Left

Question 13

Motor cortex function

Answer 13

• Planning, control and execution of voluntary movement
• Sends signals to muscles in body
• Diff regions control diff parts of body - logically organised eg foot control next to leg control

Question 14

Somato- sensory cortex function

Answer 14

• Receives sensory information from skin receptors all over body
• Responsible for producing sensations to do with pressure, touch, pain and temperature
• Some areas have more dedication from it to them than others eg finger tips and lips

Question 15

Visual cortex function

Answer 15

• Receives visual info from retina via optic nerve and thalamus (relay station)
• Responsible for processing visual input

Question 16

Auditory cortex function

Answer 16

• Concerned with hearing

- Recognising sounds and analyses speech based information

Question 17

Broca’s area function

Answer 17

• Responsible for language production

- Damage causes broca’s aphasia (limits ability to produce fluent language)

Question 18

Wernickes area function

Answer 18

• Responsible for language comprehension

- Damage causes loss of ability to understand written and spoken language
