The predominance of smooth muscle differon in a rat and fibroblastic differon in human results from specific differentiation due to the tissue functional features. Smooth muscle tissue is known to have contractile function and be able to perform temporally blocking, but not support function. We reveal the connective tissue predominance in human cervix results from the necessity to retain the fetus in uterine cavity during pregnancy in two-leg uprightness in evolution.cervixsmooth muscle cellfibroblastdifferonшейка маткигладкий миоцитфибробластдифферон[Занько Ю.В., Наумов А.Д.
