TMJ, eye, zygoma
Where are some potential locations where the temporalis tendon may refer pain?
mimics TMJ and masseter pain
Masseter muscle OINA
Origin: Zygomatic arch
Insertion: Lateral surface of ramus of mandible and coroid process of mandible
Innervation: Masseteric branch of V3
Action: Closes the jaw by elevating/closing the mandible
Temporalis muscle OINA
Insertion: Coronoid process and anterior border of mandible
Origin: Temporal fossa(bone) andfascia
Innervation: Deep temporal branches of V3
Action: It elevates the mandible and closes the jaw. The posterior fibers retract the mandible
Lateral pterygoid muscle OINA
Origin: The upper head originates from the lateral surface of the greater wing of the sphenoid bone. The lower head originates from the lateral surface of the lateral pterygoid plate of sphenoid bone
Insertion: Neck of condyle of mandible and articular disc and capsule of TMJ
Innervation: Branches of V3
Action: It opens the mouth. Acting together, they protrude mandible; acting alternatively, grinding action
Medial pterygoid muscle OINA
Origin: From the medial surface of lateral phterygoid plate of sphenoid and and pyramidal process of palatine bone (deep head) and tuberosity of mandible (superficial head)
Insertion: Lower part of the medial surface of the mandible and angle of the mandible
Innervation: Pterygoid branches of V3
Action: Elevates the mandible and closes the jaw. Acting together, protrude mandible. Acting alone, protrudes one side. Acting alternatively, grinding action
Myofacial pain: description and treatment
Referred Pain From A Tender Point To A Distant Site
Treated With Stretching Heat And Cold And Rest
Muscle Relaxants Can Be Helpful
Myalgia: description and treatment
Muscle Soreness Tender To Palpation Does Not Refer To A Distant Site Most Common Muscle Pain Responds To Stretching
Myositis: description and treatment
Muscle Inflamation.Usually due to Trauma or Infection
Treated Differently Than Muscle Tightness/Myalgia
NSAIDS
Steroids
Rest
No Stretching
