Explanation

Brain has three major parts:
Forebrain, midbrain and hindbrain.
i] Fore-brain/ cerebrum: It is the main thinking part of the brain. It is the largest and most prominent part of the brain. It is divided into right and left cerebral hemispheres by a deep groove. It is the centre of consciousness, thoughts, memory and analytical thinking. It also controls voluntary actions.
ii] Mid-brain- It acts as a coordinating unit between forebrain and hindbrain. It also controls some involuntary actions.
iii] Hind-brain - It has three main centres: Cerebellum, Pons and Medulla oblongata.
a] Cerebellum- It is responsible for precision of voluntary actions and maintaining the posture and balance of the body.
b] Pons: It is the center through which nerve impulses travels to and from the cerebellum, spinal cord and other parts of the brain. It also helps in respiration.
c] Medulla oblongata - It is the lowermost part of the brain. It contains vital centres for controlling blood pressure, respiration, swallowing, sneezing, coughing, salivation and vomiting.
