Infra-orbital artery

Looks like

A maxillary branch running forward in the floor of the eye socket and coming out on the cheek just below the eye.

What it does

Supplies the lower eyelid, cheek, upper lip, and the upper front teeth through small branches.

Keeping it well

Fractures of the eye socket floor can injure it with its nerve, leaving the cheek numb.
