Arteria Maxillaris Online

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 sphenopalatine branch is often responsible for severe posterior nosebleeds (epistaxis). 3. Anatomical Variations

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 arteria maxillaris

The artery typically originates behind the neck of the mandible and passes through the . It is traditionally divided into three distinct segments based on its relationship to the lateral pterygoid muscle :

Located behind the neck of the mandible. Key branches include the middle meningeal artery (which supplies the dura mater) and the inferior alveolar artery (supplying the lower teeth). Anatomical Course and Parts The artery typically originates

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

It is a "clinically significant" landmark during surgical procedures in the infratemporal fossa due to its proximity to vital nerves and vascular structures. and nasal cavity

Enters the pterygopalatine fossa . Its terminal branches supply the upper teeth, palate, and nasal cavity, including the infraorbital and sphenopalatine arteries. 2. Clinical Significance
