Description:
Medial pterygoid muscles, origo and insertio: posterior and lateral view. The medial pterygoid muscle has two heads: the superficial head is smaller and arises from the maxilla, while the deeper head is larger and originates from the pterygoid fossa. Origin: fossa pterygoidea (medial head) + tuber maxillae (lateral head). Insertion: tuberositas pterygoidea maxillae. Function: elevatation of the mandible. It also contributes to limited protrusion. When acting unilaterally, it assists in moving the mandible to the contralateral side. Latin labels.
