Differences between the upper and lower sides

The lower side [margo lateralis] (from B to Y in figs. 1 and 2) runs from the lower part of the base quite obliquely upward toward the anterior. The upper [margo superior] (from Z through F to A in figs. 1 and 2) (which is as much shorter than the lower as the lower is shorter than the base itself) 27 runs somewhat downward to the exterior, proceeding more or less transversely. 28 These two sides come together at an angle (between A and B in figs. 1 and 2) and bracket at their end a rather broad part of the scapula where the cervix of the scapula is seen and the depression [cavitas glenoidalis] that receives the head of the humerus. This place, then, (if it can be thought of as an angle) would be the third angle [angulus lateralis] of the scapula, since we count as the first angle [angulus superior] (Z in figs. 1, 2, 3) the upper angle of the base, and the lower the second angle [angulus inferior] (Y in figs. 1, 2, 3).
