Macromolecules play vital roles within your body. Macromolecules are large molecules within your body that serve essential physiological functions. Encompassing carbohydrates, proteins, lipids and nucleic acids, macromolecules exhibit a number of similarities.
Cerebellum. The cerebellum (infratentorial or back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
A movement is executed by muscles, bones and tendons. But is is the Brain that sends a neural message to the muscle in order for this one to move. In the brain, it is the Cerebullum that is responsible for motor control and it is the Motor Cortex in the Cerebral Cortex that is also responsible for the movement of any member in the body. Movement in the body is divided into external mobility and internal motility.
