Frontalis Superior, Lateral View

Description

Viewed from the lateral aspect of the male cerebrum, the superior frontal gyrus forms the dorsal convexity of the frontal lobe, running anteroposteriorly above the middle frontal gyrus and superior to the inferior frontal gyrus. Posteriorly, its border approaches the precentral sulcus and the precentral gyrus, where the highlighted region marks the primary motor cortex (M1) on the anterior bank of the central sulcus. Inferior and posterior to the cerebrum, the cerebellar hemispheres with their folia sit behind the brainstem, and the pons and medulla oblongata continue inferiorly toward the spinal cord. Gyri and sulci remain sharply defined across the lateral cortical surface. This lateral perspective helps separate the superior frontal gyrus proper from adjacent motor territories that are often conflated in teaching diagrams. The relationship of M1 to the central sulcus and precentral gyrus is the practical landmark for localizing deficits after middle cerebral artery stroke, and it also guides trajectory planning for craniotomy or neuronavigation when approaching lesions near the precentral region. Small distance errors here matter. Motor mapping depends on it. Use this artwork for neuroanatomy and neuroscience coursework when introducing frontal lobe topography, sulcal anatomy, and the clinical logic of motor localization, or for medical publishing figures discussing perirolandic tumors, epilepsy surgery, and stroke syndromes. It also fits patient-facing education on why weakness localizes to the contralateral motor cortex on the lateral hemisphere. Anatomical accuracy verified by SciePro's Medical Advisory Board.
