Stage/Week | Event |
---|---|
Carnegie stage 17 | chondrogenic progenitor of the humerus and the medial border of the scapula can be observed. |
Carnegie stage 18 | chondrogenic progenitor for rest of the scapula appears. |
Carnegie stage 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). |
Carnegie stage 21 | long head of the biceps tendon present |
Carnegie stage 22 | glenoid labrum (glenoid ligament) present |
Carnegie stage 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 |
