TBB ECTAL ASJPECT OF THE SCAPULA. 155 projects sharply entad between the Fs. glenoidea and the Mrg. coracoideus. extremity arises the M. coracoideus (Pig. 75). Midges.—See Fs. subscapular is. Tuberculum Bicipitale.—See Kg. 45. § 390. Description From its ^^^-. of Fig. 44.—The eotal aspect of the scapula. The principal feature of this surface is the sub- triangular lamina which projects therefrom; its direction is approximately longitudinal, but it is more nearly parallel with the longer part of the coracoid border, and it inclines in the opposite direction. It begins as a triangular elevation at the vertebral border of the scapula, and rises rapidly to about the mid- dle of the length of the bone, where its edge is thickened and roughened. From this point toward the glenoid end its eleva- tion remains nearly uni- form, but there are pro- jections which will be described presently. This ectal ridge is the mesoscapula or spine of the scapula. § 391. In the light of Embryology and Comparative Anatomy, the entire scapula may be regarded as essentially a subcylindrical bar. With most Mammals the sides are pro- duced in three directions so that a transection is irregularly T-shnped ; the upright of the T represents the ectal ridge just described, and the two arms of the cross-piece represent the two laminae at right angles therewith which constitute the principal part of the bone, and whose borders are respectively glenoid and coracoid. By Parter (A, 215), these three regions are called respectively mesoscapula, postscapula and prmscapula. Consistently with these names, the glenoid border should be called Mrg. postscapularis, and the coracoid Mrg. priBscapulfiris ; the fossse between them and the mesoscapula should also be similarly designated. Since, however, the anthropotomical name for mesoscapula is spine, and in the
