(b) Posture and Balance:
The cerebellum, a part of the brain located at the back of the skull, is primarily responsible for maintaining posture, balance, and coordinated movement. It processes sensory input from various body parts and helps regulate the coordination of voluntary movements.
The cerebellum receives signals from the inner ear (which detects changes in head position) and from the muscles and joints (which detect body position and movement). It then integrates this information and adjusts muscle activity to maintain balance and posture.
If there is a dysfunction in the cerebellum, a person may have difficulty maintaining balance, as the body loses the ability to coordinate movement properly.
Thus, the cerebellum is the part of the brain responsible for posture and balance.
