Human Brain Anatomy In Anterior Section

Description

Cerebral hemispheres are presented in a coronal (anterior) section, with the cortical gray matter forming a continuous peripheral ribbon and the underlying cerebral white matter occupying the deep centrum semiovale. Near the midline, the corpus callosum (genu and body, depending on the slice level) arches superior to the septum pellucidum, while the frontal horns of the lateral ventricles sit inferior to the callosal fibers and lateral to the interhemispheric fissure. Deep to the cortex, the basal ganglia region is suggested by paired gray masses lateral to the ventricles, separated by the internal capsule from more medial diencephalic structures when the cut passes far enough posteriorly. Left and right anatomy reads symmetrically across the midline. Coronal sections like this sit at the intersection of gross anatomy and cross sectional imaging, because they map directly onto standard MRI and CT orientations used to localize focal neurologic deficits. The relationship of the caudate nucleus to the frontal horn, and of the internal capsule to adjacent lentiform nuclei, frames classic teaching around lacunar infarcts that produce pure motor hemiparesis from corticospinal tract involvement. Ventricular caliber is also easy to judge in this plane. A quiet but practical reference. Neuroanatomy and neuroscience courses use this illustration to reinforce gray versus white matter organization, ventricular anatomy, and the midline commissural system in a single, fixed cut. It also fits radiology teaching files and neurology texts that correlate coronal anatomy with middle cerebral artery territory stroke patterns, basal ganglia hemorrhage, and hydrocephalus.
