What is the primary function of the frontal lobe?

The primary function of the frontal lobe is to initiate voluntary motor movements. This area of the brain is critically involved in executing movements, planning actions, and coordinating behavior. The frontal lobe contains the primary motor cortex, which is specifically responsible for planning and executing voluntary muscular movements.

In addition to motor control, the frontal lobe is also associated with higher-order cognitive processes, such as decision-making, problem-solving, and controlling emotional responses. However, its foremost role in the context of movement makes the initiation of voluntary motor movements its primary function. This involvement underscores the importance of the frontal lobe in not just movement but also in purposeful, goal-directed activity.
