The Digastric Muscle’s Role in TMJ Movement
The digastric muscle assists in opening the jaw and stabilizing it during swallowing and speaking. This muscle connects the lower jaw to the base of the skull, working alongside the lateral pterygoid for smooth jaw opening. Trigger points in the digastric muscle can refer pain to the throat or under the chin, mimicking symptoms of a sore throat. These patterns can complicate the diagnosis of TMJ disorders. Gentle stretching and massage can help release tension in the digastric muscle and reduce associated pain.
