Human Brain Structure. The human brain is comprised of a number of different regions. Each of these regions are vitally important with highly specialized functions. The central part of the brain includes the brain stem and the midbrain. The function of the midbrain and has been largely preserved over years of evolution.
What is the brain? The brain is the control centre for your body and it sits in your skull at the top of your spinal cord. The brain has three main parts. The cerebellum (say se-re-bell-um). The cerebrum (say se-re-brum), which has two parts, the left and right cerebral hemispheres, (say se-re-brell hem-iss-fears). The brain stem, that controls a lot of the 'automatic' actions of your body such as breathing and heart beat, and links the brain to the spinal cord and the rest of the body.
