bulbis cordis, cardiac jelly, cephalic neuropore, cephalic part of foregut, epimyocardial space, facio-vestibulocochlear neural crest (CN VII and CN VIII), laryngotracheal groove, mesocardium, notochord, otic placode, pericardial sac, pharynx, primordial endocardium, primordial epimyocardium

A section through placode VIII (otic) and cranial part of the primitive ventricle of the heart.

Observe:
1. The two layers of the heart, primitive endocardium and epimyocardium, separated by the endomyocardial space.
2. The heart tube suspended by the mesocardium.
3. The laryngotracheal groove in the floor of the foregut.
4. The close relation between the caudal part of the facioacoustic crest and placode VIII (otic), which will form the membranous labyrinth of the internal ear.
5. The caudal extent of the rostral neuropore.
