Occipital Bone, Lateral View

Description

Lateral profile of a female skull highlights the occipital bone along the posterior cranial vault, with the squamous part curving superiorly toward the lambdoid suture where it meets the parietal bone. Inferiorly, the occipital region tapers toward the cranial base near the mastoid part of the temporal bone, clarifying the occipitomastoid suture and the close surface relationship to the mastoid process. The mandible and maxilla remain in neutral occlusion anteriorly, while the upper cervical spine aligns beneath the skull, placing the atlanto-occipital region in context. Sutural boundaries are cleanly legible. Orientation like this matters when teaching how the skull base transitions into the cervical spine and where posterior cranial landmarks sit relative to surgical corridors. The asterion, near the junction of the lambdoid, occipitomastoid, and parietomastoid sutures, is a classic external reference for the transverse-sigmoid sinus region and informs planning for retrosigmoid and suboccipital approaches. Trauma workups also benefit from this lateral relationship map: occipital condyle fractures, basilar skull fracture lines tracking toward the mastoid, and atlanto-occipital dissociation are interpreted against these bony contours. Landmarks, not guesswork. Use this figure for gross anatomy lab manuals covering the neurocranium, for radiology teaching files correlating lateral skull views with CT bone windows, and for neurosurgical or otologic publications that need a clear external guide to posterior fossa entry points and skull base topography.
