The systemic arterial pattern of the guinea pig: The pelvis and pelvic limb

Abstract

The systemic arterial pattern of 59 guinea pigs was examined by dissection, angiography, or corrosion casting. The blood supply to the pelvis and the pelvic limbs arises as two terminal branches of the aorta, the right and left common iliac arteries, and each of these divides into external and internal iliac arteries. Their pattern of distribution resembles a typical mammalian pattern. The external iliac artery passes throught the body wall to supply the pelvic limb and the internal iliac artery is distributed primarily to the pelvic region and its viscera.

Blood Supply to the Abdominal and Pelvic Regions in the Mediterranean Pine Vole, Microtus duodecimcostatus (Rodentia, Arvicolidae)

“…duodecirncostatus shows, as a particular variation not previously observed in other Arvicolidae, the existence of a gastrolienal trunk in some arrangements of the coeliac axis. Similarly, the origin of the prostatic or the vaginal artery (referred to as the urogenital artery by Stump and Shively (1976)) from the pudendoepigastric trunk has not previously been reported in other rodents.…”

“…the head (Bugge, 1974) and, especially, the heart (Bisaillon, 1981;ArquC et al, 1986;Sans-Coma et al, 1989;Duran et al, 1991Duran et al, , 1992. Analysis of the vascularization of the abdominal and pelvic regions has mainly been performed in rodents used for experimental studies, such as the laboratory rat (Greene, 1968), the mouse (Cook 1965;Roberts and Holmes, 1988), the golden hamster (Michel, 1959;Orsi et al, 1977) and the guinea pig (Potter et al, 1958;Shively and Stump, 1975;Stump and Shively, 1976;Vicentini et al, 1981). New approaches in the understanding of the circulatory system in wild rodents have recently been made possible by the study of the abdominal and pelvic arterial system in some myomorph species (L6pez-Fuster and Ventura, 1992;L6pez-Fuster et al, 1993;Ventura et al, 1993;Gispert et al, 1994;Ventura and L6pez-Fuster, 1994).…”

The Arterial System of the Wood Mouse, Apodemus sylvaticus: The Pelvic Region

“…The aim of this paper is to expose data on the origin and variation of the pelvic arteries in the wood mouse, Apodemus sylvaticus. Due to the scarce information available on wild rodents, results are compared with those reported for certain domestic species (MICHEL, 1959;GREENE, 1968;STUMP and SHIVELY, 1976;VICENTINI et al, 1981).…”

Arrangement of the Branches of the Aorta Abdominalis in the Wood Mouse (Apodemus sylvaticus)

“…Although the information available on the vascular system of laboratory rodents has been extensive (SCHWARZE and MICHEL, 1957;MICHEL, 1959;POTTER et al, 1958;SHIVELY and STUMP, 1974;STUMP and SHIVELY, 1976;ORSI et al, 1977;VICENTINI et al, 1981, etc. ), relatively little has been reported concerning the arterial pattern of wild living rodent species.…”
