The brain is divisible into three main regions—forebrain, midbrain, and hindbrain.
Forebrain
It is the main thinking part of the brain. It consists of the cerebrum, thalamus, and hypothalamus.
The cerebrum is the largest part of the brain and constitutes four-fifth of its weight. The forebrain has sensory regions, which receive sensory impulses from various receptors. It also has motor regions, which control the movement of various muscles such as leg muscles. There are separate areas in the forebrain specialized for hearing, smelling, seeing, general sensations such as pain, touch, taste, etc. A certain part of the cerebrum primarily controls intelligence, learning, memory, thinking, and the ability to articulate speech. The forebrain is also known as the main thinking part of the brain.
The hypothalamus contains many areas that control the body temperature, urge for eating and drinking, etc. Some regions of the cerebrum along with hypothalamus are involved in the regulation of sexual behaviour and expression of emotional reactions such as excitement, pleasure, fear, etc.
Midbrain
It has regions that are concerned with the sense of sight and hearing. Some regions of the midbrain transmit motor impulses to the limbs.
Hindbrain
Most involuntary actions such as heart beat, blood pressure, movement of food in the alimentary canal, salivation, etc. are controlled by the midbrain and hindbrain. All these involuntary actions are controlled by the medulla of the hindbrain.
The cerebellum, which is a part of the hindbrain, is responsible for maintaining the posture and equilibrium of the body. It also coordinates the contraction of voluntary muscles, according to the directions of the cerebrum.
