Primary motor cortex

Lateral view of a human cerebral hemisphere showing the primary motor cortex as a narrow, elongated vertical band along the precentral gyrus of the frontal lobe, immediately anterior to the central sulcus. The highlighted strip is gently curved and extends from the lateral surface toward the superior margin, with gyri and sulci clearly visible on the surrounding pink-gray folded cortex. The motor strip is distinguished by a contrasting warm color, with crisp borders separating it from adjacent cortex.
