Question 4

Corticospinal fibers orginate here along with sending projections to the basal ganglia, pontine nuclei, reticular formations, red nucleus, superior colliculus, vestibular & inferior olivary nuclei as well as all brainstem nuclei

Answer 4

4

Question 5

Located in the post central gyrus of the parietal lobe

Answer 5

1,2,3

Question 6

Best known as the somesthetic cortex (body sensing)

Answer 6

1,2,3

Question 7
