Origin. The medial pterygoid originates from the pterygoid fossa of the sphenoid bone. Insertion. The medial pterygoid inserts on the pterygoid tuberosity of the mandible.. Action. Upon bilateral contractions the medial pterygoid muscles push the mandible forward. By contraction on one side the medial pterygoid muscle pushes the mandible to the opposite side..

Tap The lateral pterygoid muscle, also known as pterygoideus externus or external pterygoid muscle, is one of the muscles of mastication. Gross anatomy The lateral pterygoid is a short, thick muscle, somewhat conical in form, which extends almost Action of lateral vs. medial Pterygoid muscle "mnemonic" Look at how your jaw ends up when saying first syllable of 'Lateral' or 'Medial' : - "La" : your jaw is now open , so Lateral opens mouth. The involved muscles, which are variably enlarged and can be up to three times the normal size, are otherwise normal on all imaging studies. 2 Several case reports on combined hypertrophy of temporalis and masseter muscles were published 3 – 5 but concurrent occurrence of hypertrophy of masseter and medial pterygoid muscles is very rare.

The superior head of the lateral pterygoid can only pull disc forward if the lateral or medial discal ligaments are torn – I do not believe that the muscle alone can tear the discal ligaments if the condyles are centered in the fossa and the patient’s closure trajectory is the same as the myotrajectory.
