  2. Temporomandibular joint - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_joint

    The mesenchyme around the joint begins to form the fibrous joint capsule. Very little is known about the significance of newly forming muscles in joint formation. The developing superior head of the lateral pterygoid muscle attaches to the anterior portion of the fetal disk.

  3. Pterygospinous ligament - Wikipedia

    en.wikipedia.org/wiki/Pterygospinous_ligament

    The pterygospinous ligament stretches from the upper part of the posterior border of the lateral pterygoid plate to the spinous process of the sphenoid. Structure [ edit ]

  4. Temporomandibular joint dysfunction - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_joint...

    To theorize upon this observation, some have suggested that due to a tear in the back of the joint capsule, the articular disc may be displaced forwards (anterior disc displacement), stopping the upper head of lateral pterygoid from acting to stabilize the disc as it would do normally.

  5. Articular disk of the temporomandibular joint - Wikipedia

    en.wikipedia.org/wiki/Articular_disk_of_the...

    Posteriorly, the disc attaches superiorly to the temporal bone and inferiorly to the posterior condyle (the posterior attachments are frequently called the bilaminar zone). Laterally and medially, the disc attachments blend into the joint capsule near its attachment to the condylar head. The disc prevents the mandible from moving posteriorly. [2]

  6. Mesenchyme - Wikipedia

    en.wikipedia.org/wiki/Mesenchyme

    Mesenchyme (/ ˈ m ɛ s ə n k aɪ m ˈ m iː z ən-/ [1]) is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to most tissues, such as skin, blood or bone. [2] [3] The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo. [4]

  7. Pterygoid processes of the sphenoid - Wikipedia

    en.wikipedia.org/wiki/Pterygoid_processes_of_the...

    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 mandible to move in a lateral and medial direction, or from side-to-side.

  8. Pterygospinous process - Wikipedia

    en.wikipedia.org/wiki/Pterygospinous_process

    Pterygospinous process, also known as the Civinini process or processus pterygospinosus, is a sharp spine on the posterior edge of the lateral pterygoid plate of the sphenoid bone. The pterygospinous process is attached pterygospinous ligament which stretches towards the spine of the sphenoid.

  9. Pterygomandibular space - Wikipedia

    en.wikipedia.org/wiki/Pterygomandibular_space

    Diagram showing left medial and lateral pterygoid muscles. Part of the zygomatic arch and the ramus of the mandible have been cut away. The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus.
