Which artery is a terminal branch of the maxillary artery?

• A. Facial artery
• B. Inferior alveolar artery
• C. Infraorbital artery
• D. Transverse facial artery

Answer: (C)

The infraorbital artery is indeed a terminal branch of the maxillary artery. The maxillary artery, a major artery of the face and jaw, has several branches that supply various structures of the maxillofacial region. As it progresses through the infratemporal fossa, it gives rise to several important branches, and the infraorbital artery emerges as one of its terminal branches. This artery travels forward through the infraorbital foramen, supplying the lower eyelid, side of the nose, and the upper lip. Its role is crucial in vascularizing these areas, making it significant in both anatomical and clinical contexts related to facial trauma, cosmetic procedures, and dental interventions. The other choices relate to branches that arise from the maxillary artery but do not represent its terminal branches. The facial artery, for example, has its own distinct origin and pathway, while the inferior alveolar artery serves the mandibular teeth, and the transverse facial artery is a branch of the superficial temporal artery rather than directly from the maxillary artery. Understanding these branches in relation to their functions enhances comprehension of the vascular anatomy of the face and jaw.
