In human anatomy, the levator claviculae is a very rare[1] accessory[2] and vestigial[3] 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.[4] Though a supernumerary muscle[2] present in only 2–3% of all people, it is not an abnormality but a variant of normal human anatomy[4] with an atavistic character.[2]
It has also been referred to as the omocervicalis, cleidocervicalis, and tracheloacromial muscle, with the variation in names indicating different sites of origin and insertion.[1]
