The Lateral Pterygoid Muscle is one of the muscles responsible for jaw movement. It is located in the jaw area and plays a crucial role in opening the mouth and moving the jaw side to side. This muscle is essential for actions like chewing and speaking. Anatomically, the lateral pterygoid has two parts: the superior and inferior heads. The superior head connects to the sphenoid bone, while the inferior head attaches to the mandible. Dysfunction or injury to this muscle can lead to jaw pain and difficulty in movement, affecting daily activities.
