Carnegie Stage Event
17 chondrogenic progenitor of the humerus and the medial border of the scapula can be observed.
18 chondrogenic progenitor for rest of the scapula appears.
19 glenohumeral joint will begin delaminating and showing a looser central band (interzone). Denser lateral bands will join the humeral head (caput humeri) and the margins of the articular surface of the scapula, thus forming the glenoid labrum (glenoid ligament).
21 long head of the biceps tendon present
22 glenoid labrum (glenoid ligament) present
23 coracohumeral ligament present
Fetal Week 10 osteogenic process begins in the humeral head. Primitive glenohumeral ligament present
Fetal Week 11 osteogenic process begins in the scapula
