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.
The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum âfine-tunesâ movement. This area of the brain controls fine motor movement, balance, and the brainâs ability to determine limb position. A stroke in the cerebellum can lead to paralysis or jerky muscle movements. Located at the top of the spinal column, the brain stem controls breathing, heart rate, blood pressure, and alertness.
