Encyclopedia
At the lower part of the infratemporal surface
of the maxilla
is a rounded eminence, the maxillary tuberosity, especially prominent after the growth of the wisdom tooth
; it is rough on its lateral side for articulation with the pyramidal process of the palatine bone and in some cases articulates with the lateral pterygoid plate
of the sphenoid

It gives origin to a few fibers of the Medial pterygoid muscle

Infratemporal surface of the body of the maxilla
The infratemporal surface is convex, directed backward and lateralward, and forms part of the infratemporal fossa.It is separated from the anterior surface by the zygomatic process and by a strong ridge, extending upward from the socket of the first molar tooth...

Lateral pterygoid plate
The lateral pterygoid plate of the sphenoid is broad, thin, and everted; its lateral surface forms part of the medial wall of the infratemporal fossa, and gives attachment to the lateral pterygoid muscle; its medial surface forms part of the pterygoid fossa, and gives attachment to the medial...
