The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus. The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla. The forebrain is the most important part of brain, it distinguishes human from other animals. This part is responsible for processing sensory information, collected by different sensory organs, such as eyes, nose, ears, tongue and skin. The midbrain acts as a bridge to transmit signals from hindbrain and forebrain. The upper part of the midbrain is called optic tectum, which serves to integrate visionary and auditory data. The hindbrain can be further divided into 3 parts: medulla oblongata, pons and cerebellum. The main function of this human brain structure is to control certain visceral functions in body.
