Nervous System of the Head of an Obese Male

Description

Rendered as a transparent head in anterior oblique perspective, the male scalp and calvaria are cleared to expose the cerebral hemispheres with distinct gyri and sulci, including the frontal and temporal lobes laterally and the parietal convexity superiorly. Yellow neural tracts course from the basal surface toward the face and neck, consistent with cranial nerves emerging from the brainstem at the pontomedullary junction and from the midbrain, with their proximal segments lying inferior to the cerebral hemispheres. Along the inferomedial temporal region, the brain surface contours suggest the vicinity of the uncus and tentorial edge, key spatial references when orienting the skull base. Small details matter. Emphasis on the base of brain connections makes this view useful for teaching why cranial nerve dysfunction localizes lesions: the oculomotor nerve (CN III) runs between the posterior cerebral and superior cerebellar arteries, the abducens nerve (CN VI) is vulnerable along the clivus in raised intracranial pressure, and the trigeminal nerve (CN V) emerges from the lateral pons where schwannomas or petroclival meningiomas can distort the cisternal segment. Obesity adds real-world context, since increased prevalence of idiopathic intracranial hypertension and obstructive sleep apnea can intersect with headache, papilledema, and compressive neuropathies that prompt cranial nerve-focused exams. A clear orientation of superior, inferior, medial, and lateral relationships helps students connect bedside deficits to skull base anatomy. Use this artwork for neuroanatomy and head and neck anatomy lectures, for board-style cranial nerve pathway diagrams, or for publication figures discussing skull base approaches and neurovascular compression syndromes. It also supports patient-facing education in neurology or neurosurgery clinics when explaining why a focal diplopia or facial numbness points to a specific cranial nerve segment.
