The mylohyoid muscle is a part of a group of neck muscles from the suprahyoid group. It is one of the four extrinsic muscles, which control the tongue. The right and left side of the muscle, similar to a sling, supports the tongue. From a branch of the mandibular division, it is innervated by the mylohyoid. The location of the muscle forms from the floor of the oral cavity. It is attached to both the mylohyoid line on the internal aspect of the mandible and the hyoid bone. From both sides located in the mandible, the mylohyoid muscle arises. Each side of the mandible, enters into the midline raphe; connecting the mylohyoid muscle from the reverse side. The purpose of the mylohyoid muscle works to perform three separate functions. It depresses the mandible. The muscle raises the floor of the mouth during the first point of deglutition. Finally, it elevates the hyoid bone. This process controls the part of the tongue, which makes velar consonants and vowels.
