What is the blood supply for the TMJ intermediate zone?

  1. Maxillary artery

  2. Facial artery

  3. Superficial temporal artery

  4. Deep temporal artery

The correct answer is: Superficial temporal artery

The intermediate zone of the TMJ is supplied by the superficial temporal artery. This is because the TMJ is located near the ear and the superficial temporal artery runs along the side of the head, supplying blood to the surrounding area. B, the facial artery, is incorrect because it primarily supplies the face and not the TMJ area. A and D, the maxillary artery and deep temporal artery, respectively, are incorrect as they do not supply this specific area but rather other structures in the head and neck.
