Anatomical terminology

The occiput[help 1] is the anatomical term for the posterior (back) portion of the head or skull. In insects, the occiput is the posterior part of the head capsule.

The word occipital means "pertaining to the occiput",[2] as in the name of the occipital bone.

Clinical significance[edit]

Trauma to the occiput can cause a basilar skull fracture.

Prominent occiput is a feature of Trisomy 18 (Edward's Syndrome), along with small jaw, low-set ears, and mental retardation. It is also a feature of Trisomy 9 and Beckwith–Wiedemann syndrome.

Identification of the location of the fetal occiput is important in obstetrics.
