The cerebellum contributes by maintaining the posture, balance, and precision of these voluntary actions, allowing for smooth and coordinated movements.

The cerebellum is responsible for the precision of voluntary actions, ensuring coordinated movements such as walking in a straight line, riding a bicycle, and picking up a pencil.

The medulla in the hind-brain is mentioned as the part responsible for controlling various involuntary actions, including blood pressure, salivation, and vomiting.

The sensation of feeling full is associated with a center in a separate part of the fore-brain, specifically in relation to hunger. This center influences our awareness of being satiated.

The motor areas in the fore-brain control the movement of voluntary muscles. Once a decision is made based on sensory information, it is passed on to these motor areas for the execution of a response, such as controlling leg muscles.
