Frontal Anatomy
Subspecialty: Neuro-anatomy
Type: Clinical Summary
The cerebrum's microsurgical anatomy underpins safe access to eloquent cortex and deep structures by relating superficial landmarks to the internal architecture, vascular supply, and white matter pathways. This chapter reviews the supratentorial anatomy—surfaces, sulci, gyri, ventricular relationships, the sylvian fissure and insula—and provides the spatial relationships critical to neurosurgical planning and intraoperative navigation. Overview The paired cerebral hemispheres form the largest portion of the brain and are partitioned by the longitudinal fissure and connected by the corpus callo…
