"occiput" is tied to multiple concepts in the ontology, please choose one.

The area that is concave and surrounds the postocciput.
The area that is located on the occiput ventrally of the occipital foramen.
The area that is located posteriorly on the cranium; that extends anteriorly to the posterior margin of the vertex and the gena, the border sometimes being marked by an occipital carina; and that medially encircles the postocciput.
