  2. Mandibular fossa - Wikipedia

    en.wikipedia.org/wiki/Mandibular_fossa

    If the mandibular fossa is very shallow, this can cause problems with the strength of the temporomandibular joint. [5] This can lead to easy subluxation of the joint and trismus (lock jaw). [5] Deformation of the mandibular fossa, often part of temporomandibular dysplasia, causes similar problems in dogs.

  3. Temporomandibular joint - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_joint

    The condyle of the mandible articulates with the temporal bone in the mandibular fossa. The mandibular fossa is a concave depression in the squamous portion of the temporal bone. These two bones are actually separated by an articular disc, which divides the joint into two distinct compartments.

  4. 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.

  5. Temporal bone - Wikipedia

    en.wikipedia.org/wiki/Temporal_bone

    The mandibular fossa is at first extremely shallow, and looks lateral and inferior; it deepens and directs more inferiorly over time. The part of the squama which forms the fossa lies at first below the level of the zygomatic process.

  6. Mandible - Wikipedia

    en.wikipedia.org/wiki/Mandible

    Below the mental spine is an oval depression (the digastric fossa of the mandible) where the digastric muscle attaches. [7] Extending backward and upward on either side from the lower symphysis is a ridge called the mylohyoid line , where the mylohyoid muscle attaches; a small part of the superior pharyngeal constrictor muscle attaches to the ...

  7. Posselt's envelope of motion - Wikipedia

    en.wikipedia.org/wiki/Posselt's_Envelope_of_Motion

    Translation Translation occurs in the upper TMJ compartment and provides most of the mandible's ability to open. Articular disc and condyle complex slide inferiorly on the articular eminences, allowing maximum depression of the mandible. [7] Maximal Mandibular Opening (T). Condylar heads are said to be at a maximum anterior-inferior position.

  8. Facial skeleton - Wikipedia

    en.wikipedia.org/wiki/Facial_skeleton

    The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.

  9. Zygomatic arch - Wikipedia

    en.wikipedia.org/wiki/Zygomatic_arch

    In anatomy, the zygomatic arch, or 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 of the temporal muscle ...
