The Masseter has two parts: Superficial Layer and Deep Layer.
- Zygomatic bone and the zygomatic arch of the temporal bone to the mandible.
- The mandibular attachment is onto the angle, ramus, and coronoid process of the mandible.
- Elevates the mandible at the TMJs (entire muscle).
- Protracts the mandible at the TMJs (superficial layer).
- Retracts the mandible at the TMJs (deep layer).
- The masseter and medial pterygoid form a sling that supports the mandible.
- The masseter is often stated to be the strongest muscle in the human body.
