  2. 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).

  3. Temporomandibular joint - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_joint

    The articular capsule (capsular ligament) is a thin, loose envelope, attached above to the circumference of the mandibular fossa and the articular tubercle immediately in front; below, to the neck of the condyle of the mandible. Its loose attachment to the neck of the mandible allows for free movement.

  4. Sphenomandibularis - Wikipedia

    en.wikipedia.org/wiki/Sphenomandibularis

    The sphenomandibularis is a muscle attaching to the sphenoid bone and the mandible. [1] [2] It is a muscle of mastication. [3]Unlike most of the muscles of the human body, which had been categorized several centuries ago, the sphenomandibularis was discovered in the mid-1990s at the University of Maryland at Baltimore.

  5. Temporalis muscle - Wikipedia

    en.wikipedia.org/wiki/Temporalis_muscle

    In anatomy, the temporalis muscle, also known as the temporal muscle, is one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone. [1] Temporal refers to the head's temples.

  6. Digastric muscle - Wikipedia

    en.wikipedia.org/wiki/Digastric_muscle

    The digastric muscle (also digastricus) (named digastric as it has two 'bellies') is a bilaterally paired suprahyoid muscle located under the jaw.Its posterior belly is attached to the mastoid notch of temporal bone, and its anterior belly is attached to the digastric fossa of mandible; the two bellies are united by an intermediate tendon which is held in a loop that attaches to the hyoid bone.

  7. Condyloid process - Wikipedia

    en.wikipedia.org/wiki/Condyloid_process

    The neck of the process rises from the posterior of the ramus mandibulae. [1] It is flattened from before backward, and strengthened by ridges which descend from the forepart and sides of the condyle. Its posterior surface is convex; its anterior surface has a depression for the attachment of the lateral pterygoid muscle. [1]

  8. 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]

  9. Mylohyoid line - Wikipedia

    en.wikipedia.org/wiki/Mylohyoid_line

    The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1] Rarely, the mylohyoid muscle may originate partially from other surfaces of the mandible. [ 2 ] The posterior (back) part of this line, near the alveolar margin , gives attachment to a small part of the superior pharyngeal constrictor muscle , and to the ...
