  2. 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]

  3. Geniohyoid muscle - Wikipedia

    en.wikipedia.org/wiki/Geniohyoid_muscle

    The geniohyoid muscle is innervated by fibres from the first cervical spinal nerve travelling alongside the hypoglossal nerve. [2] [4] [5] Although the first three cervical nerves give rise to the ansa cervicalis, the geniohyoid muscle is said to be innervated by the first cervical nerve, as some of its efferent fibers do not contribute to ansa cervicalis.

  4. 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.

  5. 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).

  6. Suprahyoid muscles - Wikipedia

    en.wikipedia.org/wiki/Suprahyoid_muscles

    The mylohyoid muscles are thin, flat muscles that form a sling inferior to the tongue supporting the floor of the mouth. The geniohyoids are short, narrow muscles that contact each other in the midline. [2] The stylohyoids are long, thin muscles that are nearly parallel with the posterior belly of the digastric muscle. [2]

  7. Anterior triangle of the neck - Wikipedia

    en.wikipedia.org/wiki/Anterior_triangle_of_the_neck

    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. Mental spine - Wikipedia

    en.wikipedia.org/wiki/Mental_spine

    The inferior mental spines are the points of origin of the geniohyoid muscle, [2] one of the suprahyoid muscles, and the superior mental spines are the origin of the genioglossus muscle, one of the muscles of the tongue. Mental spines are important landmarks in clinical practice.

  9. Mylohyoid line - Wikipedia

    en.wikipedia.org/wiki/Mylohyoid_line

    The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
