Temporal Surface Of The Greater Sphenoid Wing, Inferior View

Description

Greater wing of the sphenoid dominates the frame, with attention on its temporal surface, the broad, smooth lateral area forming the posterior part of the temporal fossa. From an inferior perspective, the infratemporal crest is seen as a sharp ridge running obliquely, marking the inferior boundary of this temporal surface and separating it from the rougher infratemporal surface below. Superior and posterior continuity leads toward the squamous temporal region, while the crest tracks anterolaterally toward the zygomatic area, clarifying how the sphenoid contributes to the lateral skull wall. Temporalis muscle fibers arise from the temporal fossa and converge deep to the zygomatic arch before inserting on the coronoid process of the mandible, so the contour and limits of the temporal surface matter when teaching mastication biomechanics and temporalis-related pain patterns. The infratemporal crest is a key bony landmark because it defines where the temporalis origin transitions and where the infratemporal fossa begins, a distinction that becomes practical during lateral skull base exposure and when orienting trainees to deep spaces used in dental anesthesia discussions. Surface smoothness versus ridging reads well in a single fixed view. It helps discriminate true muscle bed from adjacent borders. Use this illustration in head and neck anatomy teaching (temporal fossa and infratemporal fossa boundaries), in neurosurgical or maxillofacial texts describing the pterional region, and in exam material that tests recognition of the sphenoid’s greater wing from an inferior angle. Good for labeling exercises. Anatomical accuracy verified by SciePro's Medical Advisory Board.
