Describe the location of the cerebellum?

Answer 1

Inferior to the occipital and temporal lobes.

Lies posterior to the pons.

Question 2

What connects the 2 cerebellar hemispheres?

Answer 7

the vermis.

Superior Cerebellar (branch of basilar).
Anterior Inferior Cerebellar.
Posterior Inferior Cerebellar (branch of vertebral).

Question 9

Describe the venous drainage of the cerebellum?

Superior and Inferior Cerebellar Veins.

These drain to the superior petrosal, transverse and straight dural sinuses.

Question 10

What could occur from damage to the cerebellum?

Answer 10
