Q

What are the features of Projection tracts?

A

Axons extend between cortex and other CNS areas outside cerebrum e.g. corticospinal tract

17
Q

What are the features of association tracts?

A

Axons stay on same side within cerebral cortex
Communication between brain areas
Can be long or short

18
Q

Where is the primary motor cortex located?

A

On the pre-central gyrus

19
Q

Where is the Primary somatosensory cortex located?

A

On the post-central gyrus

20
Q

If an area of the body is represented by a large piece of the primary motor/ somatosensory cortex it is likely:

A
  • a region of dense axon terminals

- very mobile and sensitive

21
Q

Damage to the primary motor cortex causes:

A
  • muscle weakness or paralysis in associated body part on opposite side of body to damage
22
Q

Damage to the primary somatosensory cortex causes:

A

Loss of sensation in associated body part on opposite side to damage
