Where does the trapezius insert on the scapula?

Explanation:
The trapezius attaches to the lateral third of the clavicle and the scapula at the acromion and the spine. This arrangement fits its actions: the upper part can elevate the scapula, the middle part retracts it, and the lower part helps depress and upwardly rotate the scapula. The medial border and inferior angle are inserts for other muscles (like rhomboids and serratus anterior), and the coracoid process is a site for different muscles entirely, so they don’t describe the trapezius insertion.
