The mylohyoid muscles form a paired muscular sling that forms part of the floor of the mouth. It also separates the sublingual space (and oral cavity) from the submandibular space.
origin: mylohyoid line/ridge on the internal surface of the mandible
insertion: anterior and middle fibers insert into a midline raphe that extends from the mandibular symphysis to the body of the hyoid bone, the posterior fibers extend directly to the body of the hyoid bone
- elevates the floor of the mouth (e.g. in swallowing or protruding the tongue)
mylohyoid boutonniere: defect in the midportion of the mylohyoid muscle through which sublingual glands, blood vessels, fat, etc. can herniate 1,4
