  2. 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.

  3. Mandibular fracture - Wikipedia

    en.wikipedia.org/wiki/Mandibular_fracture

    Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. [ 1 ] It may result in a decreased ability to fully open the mouth. [ 1 ]

  4. Temporomandibular ligament - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_ligament

    The temporomandibular ligament constrains the mandible as it opens, keeping the condyloid process close to the joint. [2] It prevents posterior displacement of the mandible. It also prevents the condyloid process from being driven upward by a blow to the jaw, which would otherwise fracture the base of the skull.

  5. Sphenomandibular ligament - Wikipedia

    en.wikipedia.org/wiki/Sphenomandibular_ligament

    The sphenomandibular ligament (internal lateral ligament) is one of the three ligaments of the temporomandibular joint. It is situated medially to - and generally separate from - the articular capsule of the joint. [1]: 671 Superiorly, it is attached to the spine of the sphenoid bone; inferiorly, it is attached to the lingula of mandible.

  6. Zygomatic arch - Wikipedia

    en.wikipedia.org/wiki/Zygomatic_arch

    In anatomy, the zygomatic arch (colloquially known as the cheek bone), is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon ...

  7. Muscles of mastication - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_mastication

    The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid, mylohyoid, and digastric muscles (the lateral pterygoid may play a role).

  8. Coronoid process of the mandible - Wikipedia

    en.wikipedia.org/wiki/Coronoid_process_of_the...

    Most fractures here are caused by strokes (contusion or penetrating injuries). [2] Conservative management of minor fractures can lead to trismus (lockjaw) that can later only be corrected by removing the coronoid process. [1] For serious fractures, a surgery involving open reduction and internal fixation can have good outcomes. [1]

  9. Alveolar process - Wikipedia

    en.wikipedia.org/wiki/Alveolar_process

    The alveolar process (/ æ l ˈ v iː ə l ər, ˌ æ l v i ˈ oʊ l ər, ˈ æ l v i ə l ər /) [1] is the portion of bone containing the tooth sockets on the jaw bones (in humans, the maxilla and the mandible). The alveolar process is covered by gums within the mouth, terminating roughly along the line of the mandibular canal.
