medial pterygoid plate
[ˈmi:djəl ˈ(p)teriɡɔid pleit]
The medial pterygoid plate (or medial pterygoid lamina) of the sphenoid is narrower and longer than the lateral pterygoid plate; it curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides.
