Infraorbital foramen


The infraorbital foramen is the exit of one channel of the infraorbital canal onto the surface of the face. It is a round opening just below the lower margin of the orbit. It transmits the infraorbital vessels and nerve into the face.


Infra is from the Latin meaning below. Orbital arises from the Latin orbis meaning a circle. Medieval anatomists were the first to apply this term to the eye socket. Foramen is the Latin term designating a hole-like opening. It is derived from the Latin forare meaning to bore or perforate.
