The medial and lateral pterygoid muscles of the rabbit were investigated in detail by dissection. The medial pterygoid muscle could be separated into superficial, intermediate and deep portions; and the first into two layers, and the last into anterior and posterior parts, the latter consisting of three layers. These portions arose from the inferior border of the pyramidal process of the palatine bone and the pterygoid fossa, and were inserted on the crista pterygoidea, the pterygoid tuberosity and the angular process on the medial surface of the mandible. The lateral pterygoid muscle consisted of upper and lower heads, with the maxillary artery located between them. The latter was formed of three layers. Both heads arose from the lateral surface of the greater wing of the sphenoid bone, the lateral surface and the inferolateral end of the lateral plate of the pterygoid process, the lateral surface of the perpendicular plate of the palatine bone and the pterygoid fossa, and were inserted on the medial surface of the mandibular cervix.
