• Electromyographic Response of the Inferior Head of the Human Lateral Pterygoid Muscle to Lateral Inclination of the Head and Changes in Posture.

抄録

To clarify the mechanism controlling human mandibular position as a function of lateral inclination of the head, electromyographic investigations of the muscle activities of the inferior head of the lateral pterygoid muscle (Lpt) were carried out while holding different postures with respect to the frontal plane.<BR>EMG recordings were taken at the Lpt, together with the posterior part of the temporal muscle (Tp) and the anterior belly of the digastric muscle (Dig).EMG, incisal movements, and head movements were recorded simultaneously in 15 normal subjects.<BR>When the head tilted to the side, Lpt muscle activities on the side of head tilt and Tp muscle activities on the side contralateral to the tilt increased, and the lower jaw was displaced towards the tilt.These reactions occurred when the head leaned left or right.However, these did not occur when the neck was flexed.These results indicate that reflex muscle activities are antigravity reactions and control the displaced condyle.
