The primary motor cortex

The primary motor cortex is a region in the brain responsible for controlling voluntary muscle movements. Located in the back part of the frontal lobe, it sends signals to muscles, coordinating actions like walking, speaking, and reaching. This area acts as the brain’s command center for movement, translating thoughts into physical actions. It works closely with other parts of the brain to ensure movements are precise and smooth. Damage to the primary motor cortex can result in weakness or paralysis on the opposite side of the body, highlighting its critical role in motor control.
