Pterygoid fovea

Pterygoid fovea is a small depression located on the neck of the mandibular condyle, a part of the mandible or lower jawbone. The term "pterygoid" is derived from the Greek words "pteryx" meaning "wing" and "eidos" meaning "form" or "shape". The term "fovea" is Latin for "small pit".

Anatomy

The pterygoid fovea is located on the anterior surface of the neck of the mandibular condyle. It is a small, oval-shaped depression that serves as the attachment site for the lateral pterygoid muscle, one of the muscles involved in the movement of the jaw.

Function

The primary function of the pterygoid fovea is to serve as the attachment site for the lateral pterygoid muscle. This muscle is responsible for moving the jaw forward (protrusion) and side-to-side (lateral excursion). The pterygoid fovea, therefore, plays a crucial role in these movements.

Clinical significance

Injuries or disorders affecting the pterygoid fovea can lead to problems with jaw movement. For example, a fracture of the neck of the mandible could potentially damage the pterygoid fovea, affecting the attachment of the lateral pterygoid muscle and leading to difficulties with jaw movement.
