  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. Hyoglossus - Wikipedia

    en.wikipedia.org/wiki/Hyoglossus

    Laterally, in between the hyoglossus muscle and the mylohyoid muscle, lay several important structures (from upper to lower): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.

  4. Mylohyoid muscle - Wikipedia

    en.wikipedia.org/wiki/Mylohyoid_muscle

    The mylohyoid muscle is flat and triangular, and is situated immediately superior to the anterior belly of the digastric muscle. It is a pharyngeal muscle (derived from the first pharyngeal arch) and classified as one of the suprahyoid muscles. Together, the paired mylohyoid muscles form a muscular floor for the oral cavity of the mouth. [2]

  5. Geniohyoid muscle - Wikipedia

    en.wikipedia.org/wiki/Geniohyoid_muscle

    The geniohyoid is a paired short muscle that arises from the inferior mental spine, on the back of the mandibular symphysis, and runs backward and slightly downward, to be inserted into the anterior surface of the body of the hyoid bone. [2]: 346 It lies in contact with its fellow of the opposite side. It thus belongs to the suprahyoid muscles.

    Mylohyoid: by its own nerve, a branch of the inferior alveolar (from the mandibular division of trigeminal nerve), which arises just before the parent nerve enters the mandibular foramen, pierces the sphenomandibular ligament, and runs forward on the inferior surface of the mylohyoid, supplying it and the anterior belly of the digastric.

  8. Sublingual space - Wikipedia

    en.wikipedia.org/wiki/Sublingual_space

    the mylohyoid muscle inferiorly; the medial surface of the mandible anterolaterally; the muscles along the base of the tongue (geniohyoid and genioglossus muscles) posteriorly; medially, the intrinsic muscles of the tongue and genioglossus separate the two halves of the sublingual space.

  9. Mental spine - Wikipedia

    en.wikipedia.org/wiki/Mental_spine

    A mental spine is a small projection of bone on the posterior aspect of the mandible in the midline. There are usually four mental spines: two superior and two inferior. Collectively they are also known as the genial tubercle, [1] genial apophysis and the Latin name spinae ment
