Histogenesis of human esophageal striated muscle tissue

Development of the esophageal striated muscle tissue has been studied in 60 human embryos and fetuses at the age of 6-40 weeks. Stages in differentiation of the muscle fiber have been demonstrated, process of myofibrillogenesis has been studied. In the process of differentiation of the esophageal striated muscle fiber under the basal membrane myosatellitocytes are laid. A conclusion is made about myotomic origin of the human esophageal striated muscle tissue. The developmental peculiarity of the human esophageal striated muscle is formation between muscle fibers of specialized connections. This is explained by conditions of the esophageal functioning, that realizes peristaltic movements.
