About New Models On Embryology

NEW MODELS OF EMBRYOLOGY :

1. Frontal view of the developing heart (behind the pericardial sac).

2. An oblique section extending from the roof of primitive

    atrium to the floor of ventricle showing septation.

3. An oblique section from the roof of primitive atrium

    to the floor of primitive ventricle showing formation

    of foramen secundum.

4. An oblique section from the roof of primitive atrium

    to the floor of primitive ventricle showing

    formation of foramen ovale.

5. Spiral aorto-pulmonary septum-transverse section

    (viewed from above).

6. Sagittal section through the endodermal cloaca.

7. Sagittal section through the primitive urogenital sinus.

8. Embryonic vessels, after the formation of embryonic folds.

9. Left lateral view of endothelial heart tube showing

    sacculations and formation of bulbo-ventricular loop.

10. Altered position of sacculated heart, after the formation of bulbo-ventricular loop.

11. Oblique section from the roof of sinus venosus to the floor of primitive atrium.

12. Left lateral view of the interior of atrium, ventricle and bulbus cordis.

13. Right lateral view of the interior of atrium, ventricle and bulbus cordis.

14. Interior of the bulbo-ventricular cavity and formation of inter-ventricular septum.

15. Blood streams in the bulbo-ventricular loop of heart.
