How does the TMJ primarily receive its blood supply?

The temporomandibular joint (TMJ) receives its primary blood supply from branches of the external carotid artery. This artery is responsible for supplying blood to structures in the face and neck, including several important arteries that directly supply the TMJ. The main branches that are significant to the TMJ include the maxillary artery and the superficial temporal artery, both of which branch from the external carotid artery.

The blood flow from these branches is crucial for providing nutrients and oxygen to the joint, as well as for facilitating healing and regeneration processes in the surrounding tissues. Understanding the vascular anatomy associated with the TMJ is important for diagnosing and treating conditions related to this joint, emphasizing the significance of the external carotid artery’s role in its blood supply.
