he brain is composed
of:
A. The cerebrum, which is divided
into two cerebral hemispheres. The cerebrum is the largest part of the brain and
is divided into lobes where discrete functions occur. Higher reasoning takes
place in the cerebrum.
B. The cerebellum, or little
brain, located beneath the cerebrum. The cerebellum controls coordination and
balance.
C. The brain stem, which is the
lowest portion of the brain and connects to the spinal cord, controls
involuntary functions essential for life, such as the beating of the heart and
breathing.
D. The meninges, membranes that
surround and protect the brain and spinal cord. There are three
meninges.
