The cerebellum, controlling balance and coordination, lies dorsal to the brain stem in the posterior cranial fossa, separated from the posterior base of the cerebrum by the tentorial extension of the dura.

The dura mater is the outermost of the three membranes covering the brain and spinal cord. It is dense and fibrous and firmly adherent to the inner surface of the skull. Infoldings of the dura form partitions between the cerebral hemispheres (falx {L. sickle} cerebri) and between cerebrum and cerebellum (tentorium). Within the partitions are venous channels, triangular in cross section. The dura extends around the cranial nerves.

The view of the undersurface of the brain shows the anterior poles of the temporal lobes which rest in the middle cranial fossa and the undersurface of the frontal lobes indented by the bulge of the underlying roofs of the eye sockets. The brain surface is intimately covered by the fine pia mater membrane which follows the surface into the sulci.
