The Lateral Pterygoid Muscle’s Role in TMJ Motion
The lateral pterygoid muscle is essential for opening the jaw and moving it side to side. This muscle is unique because it helps guide the TMJ forward during jaw opening, ensuring smooth movement. It also contributes to grinding motions when chewing. Trigger points in the lateral pterygoid can refer pain to the TMJ itself, causing clicking or locking sensations. This muscle’s dysfunction often contributes to TMJ disorders, making it a critical focus for treatment. Targeted exercises and trigger point release techniques can help restore normal function.
