Human Embryo (CRL 10mm) Heart

Inferior vena cava terminal in an embryo of crown-rump length 10 mm.

Panels A and K show the most caudal and cranial sides of the figure, respectively. The intervals between panels were 0.05 mm (A, B), 0.16 mm (B, C), 0.1 mm (C, D), 0.06 mm (D, E), 0.02 mm (E, F), 0.01 mm (F, G), 0.14 mm (G, H), 0.06 mm (H, I), 0.16 mm (I, J), and 0.1 mm ( J, K).

A part of the sinus venosus (SV) was observed on the left side of the inferior vena cava (IVC) (D, E), communicating with the left horn (LSVH) (arrows in panels F and G).

The left sinus horn extended cranially (H, I), continuing to the left common cardinal vein (LCCV) ( J).

The right sinus venosus horn (RSVH) opened to the right atrium (RAT) (K) 0.35 mm to the cranial side of the opening of the right common cardinal vein (RCCV) or superior vena cava (H).

ES, esophagus; LHV, left hepatic vein; LL, left lung ; LSV, left sinus valve; LSVH, left sinus venosus horn; LV, left ventricle; MHV, middle hepatic vein; PC, pericardium; RA, right auricle; RL, right lung; RSV, right sinus valve; RV, right ventricle; SP, septum primum; TR, trachea. Scale bar=1 mm.
