Description

Presented in lateral profile with a hemisection through the face and upper neck, the illustration exposes the cerebral hemispheres with their gyri and sulci superior to the tentorial region, with the cerebellum and brainstem positioned posteroinferiorly toward the foramen magnum. Anterior to the cervical vertebral column, the pharyngeal airway continues inferiorly toward the laryngeal inlet, while cranial nerves and cervical plexus elements course from the brainstem and upper spinal cord into the face and neck. Red arterial channels track along the skull base and cervical soft tissues in the expected course of the internal and external carotid systems, with blue venous drainage paralleling them toward the internal jugular vein. Orientation is immediate. Clinical teaching value comes from the way this single lateral cutaway ties surface landmarks to deep pathways that drive symptoms and operative planning. The carotid bifurcation and proximal internal carotid artery lie anterolateral in the upper neck, a relationship that underpins carotid endarterectomy exposure and explains why cervical hematoma can threaten the airway. Cranial nerve trajectories also read clearly in this projection: the trigeminal distribution across the face and the facial nerve’s course near the parotid region map directly to patterns of trigeminal neuralgia, Bell palsy, and iatrogenic injury during parotidectomy. Spatial relationships, not isolated labels, carry the point. Use it to support gross anatomy and neuroanatomy teaching on head and neck viscera, cranial nerves, and cervical vascular anatomy, or as a reference plate for atlases, board review materials, and patient education pieces on stroke, carotid disease, and cranial neuropathies. It also fits ENT and oral and maxillofacial surgery content when explaining airway anatomy and nerve-risk zones in lateral approach diagrams.
