Masseter
| origin | Superficial part: maxillary process of zygomatic bone, Inferior border of zygomatic arch (anterior 2/3) Deep part: deep/inferior surface of zygomatic arch (posterior 1/3) |
| Insertion | Lateral surface of ramus and angle of mandible |
| Innervation | Masseteric nerve of mandibular nerve (CN V3) |
| Blood supply | Masseteric artery |
| Function | Elevates and protrudes mandible |
Temporalis
| Origin | Temporal fossa (up to inferior temporal line), Temporal fascia |
| Insertion | Apex and medial surface of coronoid process of mandible |
| Action | Anterior fibres: Elevates mandible Posterior part: Retracts mandible |
