True or False: The jugular artery runs through the TMJ.

• A. True
• B. False
• C. Not Applicable
• D. Both

Answer: (D)

The key idea is understanding vascular relationships around the TMJ and recognizing that “jugular” as a vessel type refers to veins, not arteries. There is no artery named the jugular artery; the jugular vessels are veins (internal and external jugular veins) that run in the neck and drain blood from the head and neck, not through the temporomandibular joint. The TMJ is supplied by branches of the external carotid system, especially arteries like the maxillary and superficial temporal arteries, which run near the joint but do not pass through it. Venous drainage from the region goes via the pterygoid venous plexus into the maxillary vein and ultimately the internal jugular vein. So the statement is not correct—the jugular artery does not run through the TMJ.
