HAO Portal

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

The area that is delimited by the intersection of the margin of the compound eyes, the interorbital plane, and the anatomical line that is tangential to the point on the margin of the anterior ocellus which defines the minimum distance between the anterior ocellus and the oral foramen.
The dorsal area of the head, between the inner margins of the compound eyes. It is delimited anteriorly by the anterior ocellus and posteriorly by the occiput.
