Blood supply of the esophagus in the early period of human ontogenesis

Abstract

The article presents the results of the primary enlage of the esophagus in embryos 6.0-7.5 mm PCL, the formation of blood vessels in the cervical, thoracic and abdominal parts of esophagus. Purpose of the study. Find out the period of laying and forming the blood vessels of the esophagus in the early period of human ontogenesis. Material and methods. The research is based on the study of 18 embryos, 20 prefetuses and 12 fetuses by the methods of micro-micropreparation, making of topographic anatomical sections in three extraperpendicular planes, morphometry. Results. The organs and structures of the chest cavity were reconstructed, the blood supply to the cervical, thoracic, and abdominal esophagus was studied in the early period of ontogenesis. Conclusion. Blood supply of the esophagus is carried out by the arterial branches of the thyroidcervical, costal-cervical trunks, vertebral arteries and the thoracic artery, the arterial branches of the descending thoracic aorta and the left gastric artery, the left inferior diaphragm artery.
