1. Hypothalamus
2. Cerebrum
3. Midbrain
4. Cerebellum

Answer 1

Correct Answer - Option 4 : Cerebellum

Cerebellum loss of leads to decreased muscle coordination 

• The cerebellum does not controls movements, speech, sight, smell, taste, hearing, intelligence, etc.

• Activities like walking in a straight line, riding a bicycle, picking up a pencil are possible due to a part of the hindbrain called the cerebellum.
• It is responsible for the precision of voluntary actions and maintaining the posture and balance of the body.
• It is a part of the hindbrain.

• The brain has three major parts or regions, namely the forebrain, midbrain, and hindbrain.
• The forebrain is the main thinking part of the brain. It has regions that receive sensory impulses from various receptors.
• There is another set of muscle movements over which we do not have any thinking control. Many of these involuntary actions are controlled by the midbrain and hindbrain.
• All these involuntary actions including blood pressure, salivation, and vomiting are controlled by the medulla in the hindbrain.
