infraorbital groove

Not to be confused with the inferior orbital fissure, which is just lateral to the infraorbital groove.

Near the middle of the floor, located infraorbital groove, which leads to the infraorbital foramen.

Not to be confused with the infraorbital groove and infraorbital foramen, which are on opposite ends of the canal.

It traverses the infraorbital groove and canal in the floor of the orbit, and appears upon the face at the infraorbital foramen.

Near the middle of the posterior part of the orbital surface is the infraorbital groove, for the passage of the infraorbital vessels and nerve.

Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.

The infraorbital vessels are found in the inferior orbital fissure, and travel down the infraorbital groove into the infraorbital canal and exit through the infraorbital foramen.

It runs along the infraorbital groove and canal with the infraorbital nerve, and emerges on the face through the infraorbital foramen, beneath the infraorbital head of the levator labii superioris muscle.

The orbitalis muscle is a vestigial or rudimentary nonstriated muscle (smooth muscle) that crosses from the infraorbital groove and sphenomaxillary fissure and is intimately united with the periosteum of the orbit.

It transmits the infraorbital nerve as well as infraorbital artery, both of which enter this canal at the infraorbital groove and after coursing through the maxillary sinus exit via the infraorbital foramen.

The posterior superior alveolar branches (posterior superior dental branches) arise from the trunk of the maxillary nerve just before it enters the infraorbital groove; they are generally two in number, but sometimes arise by a single trunk.

Immediately above this is a smooth surface, which forms the anterior boundary of the pterygopalatine fossa, and presents a groove, for the maxillary nerve; this groove is directed lateralward and slightly upward, and is continuous with the infraorbital groove on the orbital surface.
