What is the nerve supply for the intermediate zone of TMJ?

Auriculotemporal nerve, masseteric, and deep temporal branches
Auriculotemporal nerve only
Masseteric and deep temporal branches only
Facial and trigeminal nerves

The correct answer is: Auriculotemporal nerve, masseteric, and deep temporal branches

The correct answer is A. The intermediate zone of the temporomandibular joint (TMJ) receives its nerve supply from the auriculotemporal nerve, as well as the masseteric and deep temporal branches of the mandibular nerve (V3). The auriculotemporal nerve carries sensory fibers to the joint capsule of the TMJ, whereas the masseteric and deep temporal branches provide motor innervation to the muscles involved in mastication and jaw movement. Options B, C, and D are incorrect because they do not fully encompass all the nerve branches responsible for innervating the intermediate zone of the TMJ, as mentioned in the correct answer explanation.
