Overview of the Anatomy of Levator Scalupa. The Levator scapula is a ropy extrinsic back muscle that connects the scapula to the upper cervical vertebrae through the clavicle, manubrium, first rib, and lower cervical vertebrae. Levator scapula is stretched by Forward-Head Posture, elevating and protracting the scapula. Studies show that there are statistically significant variations …
