What is the pterygoid fovea?
What is the pterygoid fovea?
The pterygoid fovea is a small depression on the anteromedial surface of the condylar process of the mandible marking the attachment of the inferior belly of the lateral pterygoid muscle.
Where does the pterygoid attach?
Medial pterygoid muscle
| Origin | Superficial part: Tuberosity of maxilla, Pyramidal process of palatine bone; Deep part: Medial surface of lateral pterygoid plate of sphenoid bone |
|---|---|
| Insertion | Medial surface of ramus and angle of mandible |
Where is the lateral pterygoid plate located?
sphenoid
The lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the …
What does the pterygoid muscle do?
The primary function of the pterygoid muscles is to produce movements of the mandible at the temporomandibular joint. Both muscles are innervated by branches of the mandibular division of the trigeminal nerve (CN V3), and receive their blood supply from branches of the maxillary artery.

Where is the pterygoid fovea located in the neck?
Pterygoid fovea. 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 .
What is the medical term for pterygoid bone?
Anatomical terms of bone. The pterygoid fovea (occasionally called pit or depression) is a concave surface on the uppermost medial side of the ramus of the mandible.
Where does the medial pterygoid muscle insert?
From their origin, the muscle fibers run posteroinferiorly and laterally, surrounding the lower fibers of the lateral pterygoid muscle. Together, the two heads of the medial pterygoid muscle insert onto the triangular impression located on the medial surface of the mandible.
What is the function of the pterygoid bridge?
It forms an attachment or bridge for the tendon of insertion of the muscle referred to as “Lateral pterygoid”. It marks the point of attachment of the inferior center of the lateral pterygoid muscle.
