Effect of the scrotal division degrees on the arterial supply distribution of native goats from the Piaui State
Keywords:Goat, Scrotum, Arterial distribuition
AbstractThe present study was design to investigate the arterial distribution of goat's scrotum with several degrees of scrotum division. We used 30 animals divided in 3 groups of 10 animals each as follow: group I: animals with simple scrotum; II animals with 50% of scrotum division; III animals with more than 50% of scrotum division. The goats were sacrificed under deep anaesthesia and the techniques for evaluate the arterial distribution were performed at the Laboratory of animal anatomy of the Federal University of Piaui. The origin of the scrotum artery was mainly from the pudenda artery (95%), follows by the superficial caudal ephigastric artery (3,3%), or had your origin as one cranial branch of the superficial caudal ephigastric artery and one caudal branches of the extern pudenda artery (1,7%). The dorsal region of scrotal septum seed two or three primary branches that provide the secondary and terminals branches, which had indiscriminate distribution into the cranial and caudal faces of the scrotum, and occasionally at the septum. The number of the terminal branches doesn't have show any difference with the scrotum configuration, however the region that corresponds to the scrotum division had more number of these branches at the animals with the greatest scrotal division.
