How do you test for pterygoid?
To palpate from outside the mouth, the head is tilted slightly to access the muscle. Palpation with one finger locates trigger points on the inner surface of the mandible by pressing upward at its angle. Palpation of the mid-belly is performed inside the mouth with the pad of the palpating index finger.
Why does my lateral pterygoid hurt?

Still, you’re probably wondering the exact relationship between your pterygoid muscle pain and a potential TMJ dysfunction.
What does the Pterygoid muscle do?
The primary function of the pterygoid muscles is to produce movements of the mandible at the temporomandibular joint. Both muscles are innervated by branches of the mandibular division of the trigeminal nerve (CN V3), and receive their blood supply from branches of the maxillary artery.
How do you examine lateral pterygoid?
Attempted palpation of what has been thought to be this structure is commonly done by placing the forefinger, or the little finger, over the buccal area of the maxillary third molar region and exerting pressure in a posterior, superior, and medial direction behind the maxillary tuberosity (Figure 2).

What nerves innervate the pterygoid muscles?
Innervation. Medial pterygoid muscle is innervated by the medial pterygoid branches of mandibular nerve (CN V3), one of the three divisions of trigeminal nerve (CN V).
How do you release the lateral pterygoid muscle?
