Fig. 18. Postnatal Human Heart Oval Fossa

The image shows a cross-section across the oval fossa (fossa ovalis, annulus ovalis) shown by double headed white arrow of a postnatal human heart. Comparison with the right hand panel of Figure 15 confirms that the cranial and posterior rim of the fossa is an infolding, while the anterior rim is the anterior buttress formed by muscularisation of the vestibular spine and mesenchymal cap.
