Which of the following is a major function of the frontal lobe?

The major function of the frontal lobe is controlling voluntary movements. This area of the brain is primarily responsible for higher-level cognitive functions, including planning, decision-making, and executing motor activity. The primary motor cortex, which is located in the frontal lobe, is specifically involved in the planning and execution of voluntary or intentional movements. When you think about moving your hand to grasp an object, for example, it is the frontal lobe that initiates and controls that action.

Understanding this function is important as it connects the brain’s physical structure with actions in the body, illustrating how specific areas are associated with certain behaviors and functions. The frontal lobe not only influences movement but also contributes to aspects of personality and executive functions, highlighting its crucial role in human behavior.
