Neuro

Question 1

Primary motor cortex area

Answer 1

area 4

Question 2

Primary sensory cortex area

Answer 2

3, 1, and 2

Question 3

Primary visual cortex area

Answer 3

area 17, either side of calcarine sulcus on occipital lobe

Question 4

primary auditory cortex area

Answer 4

area 41, transverse temproal gyrus

Question 5

Anterior association area function

Answer 5

memory, planning, and higher-order concept formation

Question 6

Posterior association area function

Answer 6

somatic sensory, visual and auditory perception and language

Question 7

Premotor cortex function

Answer 7

Receives input from the sensory association cortex and basal ganglia and output to the motor cortex

Question 8

Supplementary motor cortex function

Answer 8

• Planning of sequences of movement, coordination of sides of body.
• Active before movement and involved in initiation of motion. Lesions cause inability to initiate motions, called abulia.

Question 9

Deficit in learned, skilled motor activity, in the absence of paralysis

Answer 9

Apraxia

Question 10

Prefrontal cortex lesion would affect:

Answer 10

• Restraint (socially appropriate behavior)
• Initiative
• Order (perform sequencing tasks and other cognitive operations)

Question 11

Prefrontal cortex divisions

Answer 11

1. Dorsal (superior) prefrontal cortex
2. Medial prefrontal cortex
3. Ventral-orbitofrontal (or inferior) cortex

Question 12

Dorsal (superior) prefrontal cortex function

Answer 12

Attentional processing, planning, rule learning and memory

Question 13

. Medial prefrontal cortex and Ventral-orbitofrontal (or inferior) cortex function

Answer 13

Direct connections to the limbic system and provide the emotional component to the planned behavior

Question 14

Psterior lobe/posterior association area function

Answer 14

Attention and in the awareness of self and extra-personal space

Process the position and movement of objects, people, or self in space.

Question 15

Superior parietal lobule area and function

Answer 15

Area 5, mediates awareness of the existence and spatial relationships of body parts

Question 16

right posterior parietal cortex function

Answer 16

Orients our attention in space (important for appreciating spatial relationships)

Question 17

Supramarginal gyrus area and lesion result

Answer 17

Area 40, personal hemi-neglect

Question 18

Angular gyrus area and lesion result

Answer 18

Area 39, spatial hemi-neglect

Question 19

Constructional apraxia

Answer 19

Inability of patients to copy accurately drawings or three-dimensional constructions.

It is a common disorder after right parietal stroke.

Question 20

Gerstmann’s sydrome cause and results

Answer 20

Caused by damage to dominant parietal lobe

It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia).

It can also produce disorders of language (aphasia) and the inability to perceive objects normally (tactile agnosia).

Question 21

Visual association area and function

Answer 21

Areas 18, 19

Gives meaning and interpretation to what we see

Question 22

Wernicke’s area and function

Answer 22

Area 22, ‘sensory area’ concerned with understanding the spoken word
