Medial border of scapula
Encyclopedia
The medial border of the scapula
(vertebral border, medial margin) is the longest of the three borders, and extends from the medial
to the inferior angle.
It is arched, intermediate in thickness between the superior and the axillary borders, and the portion of it above the spine
forms an obtuse
angle with the part below.
This border presents an anterior and a posterior lip, and an intermediate narrow area.
The anterior lip affords attachment to the Serratus anterior; the posterior lip, to the Supraspinatus above the spine, the Infraspinatus below; the area between the two lips, to the Levator scapulæ above the triangular surface at the commencement of the spine, to the Rhomboideus minor on the edge of that surface, and to the Rhomboideus major below it; this last is attached by means of a fibrous arch, connected above to the lower part of the triangular surface at the base of the spine, and below to the lower part of the border.
