Arterial vascularization of the ovary, uterine tube and uterus in collared peccary (Tayassu tajacu, Linnaeus 1758) and white lipped peccary (Tayassu pecari, Link, 1795)

Abstract

It was studied the arterial vascularization of nine adult females of collared peccary, including a young and a pregnant female, and six groups of females white lipped peccary (three young and three adult). The material was obtained in the Federal University of Paraná - Campus of Palotina and in the State University of São Paulo - Campus of Ilha Solteira. The animals had the arteries injected with red-faced Neoprene latex 650 solution. The arteries supplying of the ovaries, uterine tubes and uterus are the utero-ovarica, which emits the uterine and ovarica arteries, and the vaginal arteries. The ovarica artery emits branches to the ovary, uterine tube (tubes branches) and cranial extremity of the uterine horn (tube-uterine branches) and the uterine artery emits branches for the uterine horns, uterine body and cervix. The vaginal artery emits branches for the cervix and vagina.
