lateral pterygoid muscle การใช้

Each lateral pterygoid muscle is composed of 2 heads, the upper or superior head and the lower or inferior head.
Located behind the mandibular notch and below of the condyloid process, the pterygoid fovea is located on the anterior surface of the neck of the mandible and serves for the attachment of the lateral pterygoid muscle.
Its lateral surface forms part of the medial wall of the infratemporal fossa, and gives attachment to the lateral pterygoid muscle; its medial surface forms part of the pterygoid fossa, and gives attachment to the medial pterygoid muscle.
Botulinum toxin solution ( " Botox " ) is sometimes used to treat TMD . Injection of botox into the lateral pterygoid muscle has been investigated in multiple randomized control trials, and there is evidence that it is of benefit in TMD . It is theorized that spasm of lateral pterygoid causes anterior disc displacement.
Medial to the anterior extremity of the infratemporal crest is a triangular process that serves to increase the attachment of the lateral pterygoid muscle; extending downward and medialward from this process on to the front part of the lateral pterygoid plate is a ridge that forms the anterior limit of the infratemporal surface, and, in the articulated skull, the posterior boundary of the pterygomaxillary fissure.
