Brain Viewed in a Section of the Skull, Gross Anatomy

Description

Presented within a sectioned male skull, the encephalon is visible in situ, with the telencephalon (cerebrum) occupying the anterior and superior cranial cavity and showing prominent gyri and sulci of the cerebral cortex. Inferior and posterior to the cerebral hemispheres, the cerebellum sits in the posterior cranial fossa, its folia contrasted against the smoother contours of the cerebrum. The brainstem continues inferiorly from the cerebrum and cerebellum toward the foramen magnum, aligned along the midline at the cranial base. Surrounding bone landmarks include the calvaria and cranial base, with facial skeleton elements such as the zygomatic bone and mandible, and dentition visible anteriorly. A skull section view like this clarifies how the brain’s major divisions relate to the cranial fossae, a relationship that drives both symptom patterns and surgical corridors. Mass effect from a supratentorial lesion typically shifts or compresses the cerebral hemispheres first, while posterior fossa hemorrhage or tumor can crowd the cerebellum and rapidly compromise the brainstem at the level of the foramen magnum. Clear spatial context matters. It helps explain why posterior fossa pathology can present with early ataxia, dysarthria, or obstructive hydrocephalus compared with more rostral cortical syndromes. Use this artwork in gross anatomy and neuroanatomy teaching to orient learners to the cranial cavity before introducing meninges, ventricles, or vascular territories. It also fits well in neurosurgical and neuroradiology materials that discuss compartment-based localization (supratentorial versus infratentorial) and the clinical consequences of raised intracranial pressure, herniation, and posterior fossa crowding.
