Q

Explain the somatosensory and motor homunculus areas?
What is more medial and what is more lateral?

A

Somatotopy: different parts of brain controling or receiving from different parts of the body.

Precentral gyrus: face more lateral and legs more medial side of the brain.

Region proportional to the amount of motor control. We use our mouths, hands and fingers a lot therefore the face and the hands control a large area of this.

Medial to lateral –> Feet to face.

36
Q

Explain the corticospinal tract (origin to endpoint, where it crosses over and which structures in the brainstem it will go through).

A

This process is highly conscious, you choose to make these movements occur.
