RAW DATA - The morphofunctional implications of glenoid labrum of the glenohumeral joint in hominoids

<p>Here we present the raw data for the study titled: &quot;<strong>The morphofunctional implications of glenoid <em>labrum</em> of the glenohumeral joint in hominoids&quot;.&nbsp;</strong>A morphocline of the glenoid cavity has been used to infer differences in locomotor behaviors; however, the glenoid cavity is surrounded by the glenoid <em>labrum</em>, a fibrocartilaginous structure that could influence the functionality of the glenoid. The objectives of this study are to explore the effects of the glenoid <em>labrum</em> on the area, depth, and morphology of the glenoid cavity in primates.&nbsp;Photogrammetry was used to build 3D models of the glenoid, with and without the <em>labrum</em>, and three- (3D) and two-dimensional (2D) geometric morphometry (GM) was applied. 2D areas were collected from zenithal images for glenoids with and without <em>labrum</em> to evaluate the availability of articular surface area.&nbsp;The glenoid <em>labrum</em> changes the shape, increases the depth and the surface area of the glenoid cavity, particularly in humans. Therefore, the glenoid <em>labrum</em> might hold a functional role, increasing the stability of the glenohumeral joint of primates in general, and especially in humans.</p>
