title: Morphology and development of the terminal portion of the abdominal aorta in cow during fetal and neonatal periods.
abstract: Analysis of morphological and developmental features of arteries forming the terminal portion of the aorta was performed. These are the external iliac, umbilical, median sacral, ovarian, caudal mesenteric and lumbar arteries. In the earliest fetuses slow rate of development of the branches of aorta is stated. However, beginning from 13th week ot gestation the rate increases causing considerable developmental and individual variability of the vessels. At the end of the fetal period and in newborns a decrease in the rate of the development of the terminal portion of the aorta is typical for the species and sex except individual variability of its secondary branches.
