Advanced Dental Admission Test (ADAT)

In which triangle is the facial artery located?

1. Submental triangle

2. Submandibular triangle

3. Carotid triangle

4. Muscular triangle

The correct answer is: Submandibular triangle

The facial artery is primarily located in the submandibular triangle. This triangle is situated beneath the jaw and is bordered by the mandible and the digastric muscle. The facial artery arises from the external carotid artery and follows a path that brings it into the submandibular triangle, where it supplies various facial structures. In this region, the artery can be identified as it passes deep to the submandibular gland, making this triangle significant for its anatomical relationship to the artery. The submandibular triangle also provides access to various surgical and clinical procedures, and an understanding of the facial artery's location helps in avoiding complications during such interventions. The pathway of the facial artery is also important because it supplies critical areas such as the muscles of facial expression and the skin of the face. On the other hand, the submental triangle, carotid triangle, and muscular triangle have different anatomical features and vascular contents that do not include the facial artery, which is why they are not correct responses in this context. The submental triangle primarily contains the submental lymph nodes and veins, while the carotid triangle houses major vascular structures such as the common carotid artery and internal jugular vein. Lastly, the muscular triangle primarily contains infrah
