Pterygoid process
Processus pterygoideus
Definition
The pterygoid process is a thin bony projection formed by the wings and body of the basisphenoid bone. This process is oriented sagittally. It is a paired process. Its bony extensions run rostroventrally, forming a curve.
The base of the pterygoid process contains the alar canal, which pierces it; the maxillary artery passes through this canal. The pterygoid process serves as an attachment point for muscles, such as the medial pterygoid muscle.
