Somatotopic map of the primary motor cortex

There is a broad representation of the different body parts in the primary motor cortex in an arrangement called a motor homunculus (Latin: little person). The leg area is located close to the midline, in interior sections of the motor area folding into the medial longitudinal fissure. The lateral, convex side of the primary motor cortex is arranged from top to bottom in areas that correspond to the buttocks, torso, shoulder, elbow, wrist, fingers, thumb, eyelids, lips, and jaw.
