title: [Morphology and development of the veins of the uterus in cattle during the fetal and neonatal periods].
abstract: A total of 101 specimens were used; they came from 89 fetuses (4th to 40th week of gestation) and 12 neonates (1 to 14 days old). The age of the fetuses was determined according to the method of Kantorova (1960). The uterine veins were filled with latex using an automatic injection apparatus of our own construction. The study showed that blood left the uterus of the examined animals through constantly present veins (Ramus uterinus venae ovaricae, V. uterina and Ramus uterinus venae vaginalis) as well as through a number of inconstant veins to which belonged the Vv. vaginales accessoriae craniales et caudales. The constant uterine veins and their branches differed from their adult counterparts by being morphologically more differentiated, especially by having more branches of which some disappeared with time. The uterine veins developed toward the end of the fetal period. They arose either from the most caudal Vv. mesonephridicae lumbales (V. ovarica and its branches), or from the segmental, visceral veins of the pelvis (V. uterina and Vv. vaginales).
