True- This is the course and location of the vertebral artery in the suboccipital region
128
16. The vertebral artery (include its branches if necessary): E. Both A and D of the above
Since both A and D statements are correct, answer E is the right answer for this question
129
17. The dura mater proper that separates the cerebrum from cerebellar hemispheres is: A. Falx Cerebri
False- This is the partition between the two cerebral hemispheres
130
17. The dura mater proper that separates the cerebrum from cerebellar hemispheres is: B. Tentorium Cerebelli
True- This tent-like dural partition is the one, which separates between the cerebrum and the cerebellum
131
17. The dura mater proper that separates the cerebrum from cerebellar hemispheres is:C. Falx Cerebelli
False- This relatively shallow dural partition is located between the two cerebellar hemispheres
132
17. The dura mater proper that separates the cerebrum from cerebellar hemispheres is:D. Tentorium Cerebri
*False- There is no such term in Anatomy
133
17. The dura mater proper that separates the cerebrum from cerebellar hemispheres is:E. Pituitary diaphragm
*False- This dural partition is located at the base of the brain. It separates the pituitary gland from the hypothalamus except at the pituitary stalk.
