Usually passes superficial (lateral) to the lateral pterygoid muscle in about 79.6% of cases, or deep (medial) to it in approximately 19.9%. This segment primarily supplies the muscles of mastication (masseteric, pterygoid, and deep temporal arteries).
The course of the maxillary artery can vary significantly between individuals. While most follow a lateral course relative to the lateral pterygoid muscle, some may have an (found in only about 0.01% of cases). Historically, the term "external maxillary artery" was used for the facial artery , but in modern Terminologia Anatomica , "maxillary artery" refers specifically to this deep vessel. 4. Comparison Across Species
Enters the pterygopalatine fossa . Its terminal branches supply the upper teeth, palate, and nasal cavity, including the infraorbital and sphenopalatine arteries. 2. Clinical Significance
The ( arteria maxillaris ) is a major terminal branch of the external carotid artery that provides the primary blood supply to deep structures of the face, including the upper and lower jaws, muscles of mastication, nasal cavity, and the dura mater. 1. Anatomical Course and Parts
The sphenopalatine branch is often responsible for severe posterior nosebleeds (epistaxis). 3. Anatomical Variations
In veterinary anatomy, the maxillary artery often serves as a continuation of the external carotid and can contribute to specialized structures like the (a vascular network) in certain animals such as camels, cattle, and sheep.
Surgeons must be aware of its branches, like the infraorbital artery, during dental implant surgery to avoid excessive bleeding.
