Muscles of Mastication:
- Temporal Muscle (Musculus Temporalis)
- Origin:
- Temporal fossa
○ Parietal bone – inferior temporal line
Insertion:
- Coronoid process of the mandible
Processus coronoideus mandibulae
Function:
- Elevates Mandible (Anterior Fibers)
- Retracts Mandible (Posterior Fibers)

- Masseter Muscle (Musculus Masseter)
Origin:
- Zygomatic Arch
arcus zygomaticus
Insertion:
- Masseteric Tuberocity of Mandible
tuberositas masseterica mandibulae
Function: Elevates Mandible

- Medial Pterygoid Muscle (Musculus Pterygoideus Medialis)
Origin:
Superficial Part:
Pars superficialis:
- Maxillary Tuberosity
Tuberositas maxillae

Deep Part:
Pars profunda:
- Pterygoid Fossa of Pterygoid Process
fossa pterygoidea ossis sphenoidalis

Function:
Elevates Mandible (Bilateral Contracion)
Frictional masticatory movement (Unilateral Contracion)

- Lateral Pterygoid Muscle (Musculus Pterygoideus Lateralis)

Origin:
Superior Head:
caput superius:
- Infratemporal surface + Sphenoid Bone (Greater Wing)
Facies infratemporalis + alae majoris ossis sphenoidalis
Inferior Head:
caput inferius:
Lateral Lamina of Pterygoid Process (Sphenoidal Bone)
Lamina lateralis proce
Insertion:
- Pterygoid Fovea of the Mandible
fovea pterygoidea mandibulae
ssus pterygoidei

Function:
Push mandible forward(Bilateral Contracion)
