Lateral border of the scapula
|Bone: Lateral border of the scapula|
|Left scapula. Dorsal surface. (Axillary border labeled at bottom left.}|
|Latin||margo lateralis scapulae|
|Gray's||subject #50 205|
The lateral border (or axillary border, or margin) is the thickest of the three borders of the scapula.
Immediately below the glenoid cavity is a rough impression, the infraglenoid tuberosity, about 2.5 cm. in length, which gives origin to the long head of the Triceps brachii; in front of this is a longitudinal groove, which extends as far as the lower third of this border, and affords origin to part of the Subscapularis.
