Sagittal Section of the Brain, Lateral View

Description

Presented as a lateral view of a mid-sagittal brain in an adult male, the section brings the medial cerebrum into profile with the cingulate gyrus arching superior to the corpus callosum (genu, body, and splenium) and the septum pellucidum and ventricular cavity deep to it. Inferior and posterior, the diencephalic region lies anterior to the midbrain, while the cerebellar vermis sits posterior to the pons and medulla, separated by the fourth ventricle. Cranial nerve roots emerge from the brainstem, projecting anteriorly and laterally toward the skull base and neck, with color-coded arteries, veins, and nerves helping distinguish neurovascular relationships. Midline sagittal anatomy is where students first understand how the forebrain, brainstem, and cerebellum align along a single axis, and it is also where many clinical localizations start. Lesions affecting the corpus callosum (classically in demyelinating disease or infarction in the pericallosal territory) produce interhemispheric disconnection syndromes that only make sense when you appreciate callosal topography from genu to splenium. Brainstem segmentation matters, too: the pons and medulla anchor cranial nerve nuclei and long tracts, so a lateralizing deficit paired with a specific cranial nerve palsy can be mapped back to this profile. Clean, teachable geography. Use this artwork for neuroanatomy lectures on the ventricular system, callosal commissural pathways, and brainstem divisions, or in clinical teaching materials on stroke syndromes, MS plaques, and posterior fossa mass effect with fourth ventricle compression. It also suits textbook spreads and patient-facing neurology consult handouts where a single sagittal plate clarifies “what sits above what” without overloading the viewer.
