Posterior View Of Skull

Posterior view of the Skull:
Bones that are visible from the posterior view of the skull are the Occipital bone and Paired Parietal and Temporal bone.





Occipital Bone forms most of the posterior and inferior (base) part of the skull. The squamous part of the occipital bone articulates superiorly with the paired Parietal bones at the Lambdoid suture and laterally with the temporal bone (mastoid part of temporal bone) at the occipitomastoid suture.
Posteriorly there is a midline projection called the external occipital protuberance which gives attachment to muscles and the ligamentum nuchae.  Superior and inferior to it on either side are the Superior Nuchal line and Inferior Nuchal line respectively. Most prominent feature of external occipital protuberance is the inion.
Point where the saggital suture meets the lambdoid suture is called the Lambda.
