Pterygoid fovea

From Wikipedia, the free encyclopedia

Pterygoid fovea

Medial side of mandible. (Pterygiod fovea not labelled, but indicated as the insertion for the pterygoideus externus on the upper left.)
Latin	fovea pterygoidea

The pterygoid fovea (occasionally called pit or depression) is a concave surface on the uppermost medial side of the ramus of the mandible.

Located behind the mandibular notch and below of the condyloid process, the pterygoid fovea is located on the anterior surface of the neck of the mandible and serves for the attachment of the lateral pterygoid muscle.

Not to be confused with the pterygoid fossa of the sphenoid bone.
