Accessory muscles
Do not serve as muscles that primarily act during chewing
Facial + neck muscles
Buccinator
Digastric

Origin of temporalis muscle
From partial bone of the skull
Temporal fossa
Insertion of temporalis muscle
Coronoid process of mandible
Functions of temporalis muscle
Elevation mandible
Retraction mandible
Post fibers draw mandible backwards after it has been protruded
Side to side grinding movement
Origin of masseter muscle
Lower part off lateral surface of ramus of mandible and angle of mandible
Function of masseter
Elevation of mandible
Lateral movements of mandible for efficient chewing and grinding of food
Unilateral chewing
Retraction of mandible
Origin of lateral pterygoid muscle
Upper head - infratermpoal surface and crest of greater wing of sphenoid bone
Lower head - lateral pterygoid plate
Insertion of lateral pterygoid muscle
Pterygoid fovea on ant surface of neck of mandible
Ant margin of articualr disc and capsule of TMJ
Function of lateral pterygoid muscle
Depresses mandible
Protrudes it forward for opening of jaw
Side movement
Origin of medial pterygoid
Deep head the lateral pterygoid plate, and from maxillary tuberoisty
Insertion of medial pterygoid muscle
Medial surface of angle of mandible
Functions of medial pterygoid muscle.
Medial surface of angle of mandible
Function of medial pterygoid muscle
Elevates mandible
Closes jaw
Helps in side to side movement
Myofascial release
Releasing tension in your facial tissues and muscles
Pain management
Soreness may be reduced and your tissues may start to recover
Increase movement
The range of motion in your muscles and joints may imporve
Improved circulation
Blood and oxygen may move more efficiently throughout your body
Relaxation
Massage therapy has been shown to help your body relax and loosen knots
Stress management
Tension throughout your body may be released
How to perform Myofascial release
Locate fascia tissues throughout the face = stiff and tight = trigger points/knots
Gentle,constant pressure , contact = directly on skin
Pressure = applied slowly, attempt to release and lengthen the fascia
Feel pressure and tension release and then move on to a different spot
