which part of the scapula serves as an attachment site for both the rhomboids and serratus anterior?
the vertebral border
the rhomboids work collectively with the levator scapulae muscles to elevate the medial border of the scapula, downwardly rotating the scapula with respect to the glenohumeral joint. antagonists to this function (upward rotators of the scapulae) are the serratus anterior and lower fibers of the trapezius. if the lower fibers are inactive, the serratus anterior and upper trapezius work in tandem with rhomboids and levators to elevate the entire scapula.

rhomboid major muscle
functional demands have resulted in the evolution of individual muscles from the basal unit formed by the serratus anterior. in primitive life forms, the main function of the axioscapular group is to control the movements of the vertebral border of the scapula: fibers concerned with the dorsal movement of scapula evolved into the rhomboids, those with ventral motion into serratus anterior, and those with cranial movements into levator scapulae. the evolution of the serratus anterior itself has resulted in (1) grouping of its distal and proximal fibers, (2) size reduction of its intermediate fibers, and (3) the insertion of its dominant superior and inferior parts onto the superior and inferior angles of the scapula.
