Occipital Region of the Male Head, Lateral View

Description

Seen in lateral profile, the adult male occiput forms the posterior convexity of the calvaria where the occipital bone meets the parietal bone at the lambdoid suture and continues inferiorly toward the external occipital protuberance. The occipital region lies posterior to the auricle and mastoid process of the temporal bone, with the superior nuchal line sweeping laterally toward the mastoid region. Superiorly, the vertex transitions into the parietal eminence; inferiorly, the contour approaches the nuchal area overlying the upper cervical spine. Clean bony topography. Surface anatomy of the occipital region matters because it is where clinicians localize scalp and skull trauma, and where pain generators in occipital neuralgia are often mapped relative to the superior nuchal line and occipital protuberance. In head injury assessment, a lateral view helps communicate the typical impact sites associated with occipital blows and the relationship of the occipital squama to overlying scalp layers that can hide substantial subgaleal hematoma. It also supports teaching of sutural anatomy, since the lambdoid suture can be mistaken for a skull fracture on imaging when its serrated margins are not appreciated. Use this artwork in gross anatomy and surface anatomy teaching modules, neurology and pain medicine handouts on occipital neuralgia and greater occipital nerve blocks, and in emergency medicine or radiology publications illustrating occipital trauma landmarks and calvarial sutures.
