    Development and teratology of cardiovascular and lymphatic systems Repetition: Muscle tissue Beginning of the cardiovascular system development – the 3rd week: Hemangiogenesis (day 15 – 16) – blood islets (insulae sanguinae) in extraembryonic mesoderm and splanchnic mesenchyme of embryo Clusters of mesenchyme cells (angiogenic cells) differentiate into: - angioblasts endothelium (at the periphery of blood islets) - hemoblasts primitive erythrocytes (in the center of blood islets) Clusters of angiogenic cells form a "horseshoe-shaped" space between somatic and splanchnic layer of mesoderm = pericardial cavity. Two endothelial tubes arrise in splanchnic mesoderm. The ventral portion of these tubes forms the cardiogenic area with two heart tubes, while the lateral portions form the dorsal aortae. Germ disc: prosencephalon mesencephalon eye rhombencephalon heart lateral mesoderm somites small blood vessels blood islands 8,9 Spine primitive streak Initially, the cardiogenic area is located anterior to the prechordal plate and the neural plate. The growth of the central nervous system pulls the cardiogenic area and prechordal plate (buccopharyngeal membrane ventrally and caudally ( ). Cardiogenic region just cranial to the prechordal plate. The canalization of cardiogenic clusters in the splanchnic mesoderm results in the formation of the paired heart tubes. Folding of embryo and primitive gut separation from yolk sac.

Pandit COLLEGE, AKOLA (MAHARASHTRA), INDIA. PROF. & HEAD OF DEPT., DEPARTMENT OF PHYSIOLOGY, GOVT.MEDICAL COLLEGE, Dr. G. G. Aatram AKOLA (MAHARASHTRA), INDIA. ABSTRACT Background: The coronary sinus collects majority of venous blood from the heart & return it to the right atrium of the heart. Few studies were reported on coronary venous system till now. The present study is planned to study the formation, tributaries, length & shape of coronary sinus, and shape, length and breadth of coronary sinus ostium (Thebesian valve). Materials and Methods: Thirty eight formalin xed cadaveric hearts were used for the study. The formation, tributaries, length and shape of coronary sinus (CS) was noted. The length of CS in millimetres was measured from the union of great cardiac vein and left marginal vein up to the opening of the coronary sinus in the right atrium with vernier calliper. The shape of the coronary sinus ostium was noted & the measurements (length and breadth) of it were taken in millimetres with vernier calliper. Results: In 89.47% (34) specimens the coronary sinus was formed by the union of great cardiac vein and left marginal vein.
