Base of Brain and Cerebellum

Base of the brain and cerebellum, together with the cranial nerves.

The brain and the cranial nerves seen partly in section and partly in side view. Labels: C, convolutions of the cerebrum; Cbl, cerebellum in section; MD medulla oblongata: Sp N, spinal nerve. The numbers indicate the twelve pairs of cranial nerves in order.
