The motor cortex is located in the posterior part of the frontal lobe. It is involved in planning, controlling, and executing voluntary motor functions. Regions of the motor cortex correspond to different body regions, with more precise areas occupying larger regions. Key substructures include the posterior parietal cortex for transforming visual input into motor commands, the premotor cortex for proximal movement control, and the supplementary motor area for complex coordination. The posterior parietal cortex is located in the parietal lobe but is still considered part of the motor cortex due to its function of transforming visual information into motor commands.
2. Location The Primary Motor Cortex is the posterior part of the frontal lobe, lying behind the prefrontal cortex and in front of the sensory cortex.

5. Special Note The Posterior Parietal Cortex (PPC) is located on the parietal lobe, behind the Sensory Cortex and in front of the Occipital lobe. There fore it is not part of or even adjacent to the PrecentralGyrus where the Primary Motor Cortex is located. The Posterior Parietal Cortex is still considered anatomically part of the Motor Cortex due to its function: transforming visual information into motor commands. What is the relation between the location of the PPC and its function?
