What is attached to the pterygoid hamulus?

What is attached to the pterygoid hamulus?

The pterygoid hamulus is a hook-like process at the lower extremity of the medial pterygoid plate of the sphenoid bone of the skull. It is the superior origin of the pterygomandibular raphe, and the levator veli palatini muscle….

What is the function of the pterygoid plate?

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.

What attaches to pterygoid plates?

The anterior opening of the pterygoid canal also sits on the anterior aspect of the root of the pterygoid process. The pterygoid hamulus has two important relations, related to its function: tensor veli palatini tendon passes immediately behind it. superior attachment of the pterygomandibular raphe.

What attaches to the hamulus?

The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles.

What is a hamulus in anatomy?

In vertebrate anatomy, a hamulus is a small, hook-shaped portion of a bone, or possibly of other hard tissue. In human anatomy, examples include: pterygoid hamulus. hamulus of hamate bone. lacrimal hamulus.

Is pterygoid a skull bone?

The pterygoid is a paired bone forming part of the palate of many vertebrates, behind the palatine bones. It is a flat and thin lamina, united to the medial side of the pterygoid process of the sphenoid bone, and to the perpendicular lamina of the palatine bone.

What is a Pterygoid plate fracture?

Importance: Classically, pterygoid plate fractures have been associated with fractures of the mid-face and skull base. When isolated pterygoid plate fractures are identified on imaging that only extends to the level of the skull base, other related facial fractures may be missed.

What is a Pterygoid process?

Definition of pterygoid process : a process extending downward from each side of the sphenoid bone in humans and other mammals.

Where is the hamulus located on the pterygoid?

The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each … Pterygoid Hamulus Bursitis: A Rare Intra-Oral Pain Syndrome J Craniofac Surg. 2019 Oct;30(7):e643-e645.doi: 10.1097/SCS.0000000000005700. Authors

What are the processes of the pterygoid plate?

At the inferior tip of the medial pterygoid plate is the small hook-shaped process, the pterygoid hamulus. The spaces separated the medial and lateral plate are pterygoid fissure inferiorly and pterygoid fossa posterosuperiorly. The lateral aspect of the lateral pterygoid plate forms the medial wall of the infratemporal fossa.

What kind of pain does pterygoid hamulus bursitis cause?

Pterygoid hamular bursitis is a rare craniofacial pain syndrome used to describe palatal and pharyngeal pain due to an enlarged pterygoid hamulus. The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each …

Where is the hamulus located on the sphenoid bone?

The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles.
