The posterior (back) surface of the pons forms part of the wall of the fourth ventricle of the brain.

Brain stem: The brain stem is the stalk of the brain below the cerebral hemispheres. It is the major route for communication between the forebrain and the spinal cord and peripheral nerves. It also controls various functions including respiration, regulation of heart rhythms, and primary aspects of sound loc...

Cerebrum: The cerebrum or telencephalon, together with the diencephalon, constitute the forebrain. It is the most anterior or, especially in humans, most superior region of the vertebrate central nervous system. "Telencephalon" refers to the embryonic structure, from which the mature "cerebrum" develops. The ...
