Anatomy of the Brain

Question 1

What are the lobes of the brain and their primary function?

Answer 1

Frontal - movement, associated with reasoning, planning, motor aspects of speech

Parietal - perception of sensory stimuli, orientation and recognition

Occipital - visual processing

Temporal - perception and recognition of auditory stimuli, memory (long term) and receptive language

Question 2

Where is the primary motor cortex located?

Answer 2

In front of the central sulcus

Question 3

Where is the supplementary motor cortex located?

Answer 3

In front of the primary motor cortex

Question 4

Where is the pre motor cortex located?

Answer 4

Next to the supplementary motor cortex

Question 5

Where is the Broca’s area?

Answer 5

In the frontal lobe

Question 6

Where is the primary sensory cortex located?

Answer 6

The frontal most portion of the parietal lobe

Question 7

Where is wernicke’s area located?

Answer 7

In the temporal lobe, on the left side.

Question 8

Describe the process of playing a tennis shot

Answer 8

1 - pre frontal area decides what shot should be played and how to move

2 - pre motor cortex plans the movement for trunk and girdles, responds to external stimuli i.e seeing the ball

3 - supplementary motor cortex organises sequence of muscle movements

4 - primary motor cortex generates the voluntary movement

Question 9

What cells produce myelin in the CNS and PNS?

Answer 9

PNS - schwann cells
CNS - oligodendrocytes
