Answer the following question please.

Dear student,
Please find below the answer:

The brain is divided into three parts- Forebrain, midbrain and hindbrain.



 

Forebrain: It has a crucial role to play in the thinking process. It consists of the cerebrum, thalamus, and hypothalamus.

The cerebrum is the largest part of the brain and constitutes four-fifths of its weight.  It has sensory as well as motor regions, which function in controlling the movement of various muscles such as those present in legs. Separate areas for hearing, smelling, seeing, and for general sensations like pain, touch etc. are present in the forebrain.  A certain part of the cerebrum primarily controls intelligence, learning, memory, thinking, and the ability to articulate speech. 

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: The regions of the midbrain are concerned with sight and hearing sensibilities. Some regions of the midbrain transmit motor impulses to the limbs.

Hindbrain: Most involuntary actions such as heartbeat, 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.

Hope this clears your doubt.
Regards.
