What is the name of the major artery supplying the maxillary teeth and tissues?

1. Inferior alveolar artery

2. Superior alveolar arteries

3. Submandibular artery

4. Facial artery

The correct answer is: Superior alveolar arteries

The major artery supplying the maxillary teeth and surrounding tissues is indeed the superior alveolar arteries. These arteries are branches of the maxillary artery, which is one of the terminal branches of the external carotid artery. The superior alveolar arteries consist of anterior, middle, and posterior branches, each of which supplies different portions of the upper jaw. The anterior superior alveolar artery, for instance, supplies the maxillary incisors and canines, while the posterior superior alveolar artery provides blood to the molars. This vascular supply is essential for nourishing the teeth and the supporting structures, playing a critical role in dental health. In contrast, other arteries listed may supply different regions or structures. The inferior alveolar artery primarily serves the mandibular teeth, the submandibular artery supplies the submandibular gland and surrounding tissues, and the facial artery is more focused on the facial structures rather than specifically the maxillary area. Thus, the superior alveolar arteries are specifically designed for the vascular needs of the maxillary teeth and tissues.
