Greater palatine artery

Greater Palatine Artery

The Greater Palatine Artery is a blood vessel located in the human mouth. It is one of the branches of the maxillary artery, which is itself a branch of the external carotid artery. The greater palatine artery supplies blood to the hard palate and the nasal septum.

Etymology[edit | edit source]

The term "Greater Palatine Artery" is derived from the Latin words "palatum" meaning "roof of the mouth" and "arteria" meaning "windpipe, artery". The "greater" part of the name is used to differentiate it from the lesser palatine arteries.

Anatomy[edit | edit source]

The greater palatine artery originates from the third part of the maxillary artery in the pterygopalatine fossa. It descends through the greater palatine canal to the hard palate, where it divides into smaller branches. These branches supply the gums, the hard palate, and the nasal septum.

Clinical Significance[edit | edit source]

The greater palatine artery is important in several surgical procedures involving the mouth and nose. For example, it may be ligated during a Le Fort I osteotomy to prevent excessive bleeding. It is also important in the vascular supply to flaps used in oral and maxillofacial surgery.

Related Terms[edit | edit source]

Pterygoid Plexus: This is a venous plexus that drains the areas supplied by the maxillary artery and its branches, including the greater palatine artery.
Sphenopalatine Artery: This artery is a branch of the maxillary artery that supplies the nasal cavity.
