Muscles of Mastication Flashcards
The muscles of mastication, their origin and insertion.
Temporalis Origin
Temporal Lines: Frontal/Parietal
Temporalis Insertion
Coronoid Process (Superior Portion of Mandible, Anterior to Mandibular Condyle)
Digastric Origin
Digastric Groove (Mastoid Portion of Temporal, Posterior and slightly anterior to Mastoid Process)
Digastric Insertion
Digastric Fossa (Posterior Portion of Mandible Body)
Medial Pterygoid Origin
Pterygoid Fossa (Fossa In-between Medial and Lateral Pterygoid Plates at the Posterior Portion of the Sphenoid)
Medial Pterygoid Insertion
Pterygoid Tuberosities/Internal Angle (Interrupt the Medial Surface of the Gonial Angle on Mandible Posterior to Mylohyoid Groove)
Lateral Pterygoid Origin
Lateral Pterygoid Plate (Posterior Portion of Sphenoid)
Lateral Pterygoid Insertion
Internal Aspect of Mandibular Condyle (Mandible)
Masseter Origin
Zygomatic Arch (Zygomatic)
Masseter Insertion
Masseteric Tuberosities/External Angle (Raised Lateral Edge of the Gonial Angle on Mandible)
