Temporal Surface Of The Human Temporal Bone, Lateral View

Description

Squama temporalis and its facies temporalis fill the frame in lateral view, emphasizing the smooth, convex outer surface that forms the inferior wall and floor of the temporal fossa. Superiorly, the contour sweeps toward the temporal lines on the adjacent parietal bone, while posteriorly it approaches the squamous suture (sutura squamosa) where the temporal bone overlaps the parietal. Anteriorly, the squamous part narrows toward its articulation with the greater wing of the sphenoid and continues into the zygomatic process, which projects anteroinferiorly toward the zygomatic bone. Bone surface detail is restrained. Temporalis muscle anatomy is the teaching point that benefits most from this fixed lateral perspective: the muscle belly occupies the temporal fossa and converges deep to the zygomatic arch, so the breadth and convexity of the temporal surface help explain both muscle bulk and the limited working corridor in a pterional or frontotemporal craniotomy. The pterion region lies anterosuperior to this area at the junction of frontal, parietal, temporal, and sphenoid bones, a landmark used in emergency burr-hole placement for suspected epidural hematoma, even though the bleeding source is typically the middle meningeal artery on the endocranial surface. Expect users to pair this view with internal cranial base plates to connect external landmarks to intracranial risk. Anatomy instructors can drop this illustration into head and neck lab manuals when introducing the temporal fossa, zygomatic arch, and temporalis muscle attachments, or into neurosurgical teaching slides when orienting trainees to the lateral skull at the level of the pterion and squamous temporal bone. Medical publishers will also find it well suited for concise atlases covering cranial sutures and the lateral cranial wall. Anatomical accuracy verified by SciePro's Medical Advisory Board.
