What area at the rear of the frontal lobes helps in controlling voluntary movements?

The motor cortex, located in the frontal lobes of the brain, is primarily responsible for the planning, control, and execution of voluntary movements. The structure of the motor cortex is organized in a way that includes a map of the body, often referred to as the homunculus, which illustrates how different areas correspond to different parts of the body's musculature. This mapping allows for precise control of movements, enabling the coordination of complex actions such as walking, talking, and writing.

In contrast, the sensory cortex located in the parietal lobes is responsible for processing sensory information from the body, while association areas integrate information from various modalities but do not directly control movement. The agnosia region pertains to the inability to recognize and process sensory stimuli, which is not related to the execution of voluntary movements. Thus, the motor cortex is the area that best fits the description of controlling voluntary movements at the back of the frontal lobes.
