概要

TLDRThe maxillary artery is a critical vessel in the head and neck, functioning as the largest terminal branch of the external carotid artery. It divides into three sections—mandibular, pterygoid, and pteropalatine—and supplies various structures including the external and middle ears, the jaw, teeth, and important regions within the nasal and oral cavities. Each part gives rise to significant branches, which innervate muscles and tissues across these areas. The artery plays a vital role in maintaining vascular supply to the face and is also associated with conditions such as epistaxis, particularly through its sphenopalatine artery.

収穫

  • 🦷 Supplies blood to the jaws, teeth, and associated muscles.
  • 👂 Provides blood to the external and middle ears.
  • 🤝 Divided into three parts: mandibular, pterygoid, pteropalatine.
  • 🔄 Key branches include the inferior alveolar artery and infraorbital artery.
  • 🌬️ The sphenopalatine artery is linked to epistaxis (nosebleeds).
  • 💉 Several branches supply structures in the nasal cavity and palate.

    The maxillary artery, the largest terminal branch of the external carotid artery, supplies various structures including the ears, jaws, teeth, and regions of the face. It is divided into three parts for descriptive purposes: the mandibular part, which runs horizontally forward; the pterygoid part, which runs upward and forward; and the pteropalatine part, which passes through the pterygomaxillary fissure to enter the pteropalatine fossa. Each part has specific branches that supply distinct anatomical areas, such as the deep auricular artery supplying the external acoustic meatus and the inferior alveolar artery supplying the mandible and teeth. The second part primarily gives off muscular branches, while the third part supplies the maxilla and nasal cavity. Additionally, the phopalatine artery, a terminal branch, is notable for its association with epistaxis.
