Infraorbital Artery (Noun)
Meaning
An artery that originates from the maxillary artery and supplies structures below the orbit (from lower eyelid to upper lip).
Classification
Nouns denoting body parts.
Examples
- The infraorbital artery emerges from the infraorbital foramen, from which it then makes its way downward and outward to provide blood supply to surrounding facial structures.
- The infraorbital artery passes through a small opening near the nose called the infraorbital foramen at a 45-degree angle.
- Branches of the infraorbital artery will then pass to the side of the nose, supply the area between the nose and the mouth through the nasolabial fold, up into the medial angle of the eye, as well as downwards through the cheek close to the facial surface, supplying blood to the area around the mouth.
- This particular artery covers quite a bit of area, branching off into smaller capillaries through areas such as the inferior part of the medial palpebral, to lacrimal, to jugular veins then a bit to the lateral nasal branches.
- Originating from its position off the maxillary artery, the infraorbital artery enters the orbit by the infraorbital fissure, continuing forward in the infraorbital groove and canal to emerge onto the face, where it supplies the palpebral, nasal, and labial regions, and anastomoses with branches of the facial artery.
