Question 13

What are the 3 types of functional areas?

Answer 13

Motor areas (control voluntary movement)
Sensory areas (conscious awareness of sensation)
Association areas (integrate diverse information)

Question 14

What does the primary motor cortex do

Answer 14

conscious control of precise, skilled, voluntary movements

Question 15

What does the premotor cortex do

Answer 15

• controls learned, repetitious, patterned motor skills
• coordinates simultaneous or sequential actions
• involved in planning of movements that depend on sensory feedback

Question 16

What does Broca’s area do

Answer 16

directs muscles of the tongue in speech and is active as one prepares to speak

Question 17

What does the frontal eye field do

Answer 17

controls voluntary eye movements

Question 18

What does the primary somatosensory cortex do

Answer 18

receives sensory info from the skin, skeletal muscles, joints, and is capable of spatial discrimination

Question 19

What do the visual areas do

Answer 19

receives visual info from the retinas

Question 20

What does Wernicke’s area do?

Answer 20

comprehends spoken language and recognizes familiar sounds and words (communicates with Broca’s area when repeating back what was just said/heard)

Question 21

What do the auditory areas do?

Answer 21

interprets info from inner ear as pitch, loudness, and location

Question 22

What does the olfactory cortex do

Answer 22

conscious awareness of odors

Question 23

What does the gustatory cortex do

Answer 23

involved in the perception of taste
