Functions of medulla and cerebellum: Medulla helps in controlling involuntary actions like blood pressure, salivation & vomiting. Cerebellum is responsible for precision of voluntary actions and maintaining the posture & balance of the body.

What body functions does the cerebellum control?

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.

What is responsible for involuntary actions?
