It forms the anterior part of the cheek or the lateral wall of the oral cavity. It arises from the outer surfaces of the alveolar processes of the maxilla and mandible, corresponding to the three pairs of molar teeth; and behind, from the anterior border of the pterygomandibular raphé which separates it from the constrictor pharyngis superior. It is attached upon the buccinator crest as far forward as the first molar tooth. The fibers

Levator claviculae muscle In human anatomy, the levator claviculae is a very rare accessory and vestigial skeletal muscle in the posterior triangle of the neck. It originates on the transverse processes of the upper cervical vertebrae and is inserted in the lateral half of the clavicle. Though a supernumerary muscle present in only 2–3% of all people, it is not an abnormality but a variant of normal human anatomy with an atavistic character. It has also been referred to as the omocervicalis, cleidocervicalis, and tracheloacromial muscle, with the variation in names indicating
