Complete information on the structure of human Hindbrain, Midbrain and Forebrain? Unlike the spinal cord, the human brain is a very complex structure. As such, it is very difficult to know the different structures of the brain and the functions they carry out. However, physiological psychologists have evolved some methods through which it is now possible to study some of the important structures of the brain and the functions they carry out. Brain controls almost all the activities that we do, except of course the reflex activities, which are controlled by the spinal cord. Brain controls perception, learning, thinking, and different types of motor activities. Specific regions of the brain have been identified by scientists, which control specific behavior patterns. All the regions of the brain act in close cooperation with one another. Now, let us examine these different regions of the brain as they control different functions. We shall limit our discussions to some of the important structures of the brain only. We shall begin with the back of the head, where the spinal cord rises to meet the brain. Gradually we shall come to discuss the front and upper portion of the brain through the middle. The brain can be divided into three main parts: the hindbrain, the mid brain and the fore brain. The Hindbrain The backside of the brain is called the hindbrain. It has three sub divisions: medulla, cerebellum and pons. Medulla: It is also called as medulla oblongata. This structure is the most caudal (lowest) portion of the brain stem. It is a link between the brain stem and the spinal cord. 12 layers of nerves extending from the medulla connect some vital regions of the body; such as hearts, lungs, intestine, bladder, etc. Therefore, medulla controls such vital and autonomic functions such as respiration, circulation of blood, digestion of food, etc. It also plays a
