The Lateral Pterygoid has two heads: Superior Head and Inferior Head.
- Sphenoid bone to the mandible and temporomandibular joint (TMJ).
- Having attachments directly into the articular structures of the TMJ, the lateral pterygoid is especially important to assess and treat in clients who have any sort of TMJ dysfunction.
- The lateral pterygoid is so-named because it attaches onto the sphenoid bone more laterally than the medial pterygoid.
