40 pelvic preparations of rabbits (oryctolagus cuniculus) were bilaterally studied by dissection under the stereomicroscope and angiography. The arterial pattern of the pelvis, i.e. origin and branching of the umbilical, urogenital and internal pudendal arteries (visceral branches), is described. The main characteristics observed are as follows: (1) The umbilical artery is permeable in adults and gives origin to the cranial vesical artery and a caudal branch that irrigates the pelvic urogenital organs and, eventually, the rectum, with six patterns of branching in both sexes. (2) Usually, the urogenital artery is the continuation of the visceral branch of the internal iliac artery. In 1 animal, unilaterally, it arises from the median sacral artery. In 12 animals (6 bilaterally and 6 unilaterally) the urogenital artery is absent. When present, it forms two branches, a cranial and a caudal one, that irrigate of the urogenital organs in both sexes. (3) The internal pudendal artery is the direct continuation of the internal iliac artery and gives to rise to some visceral branches that irrigate the penis, bulbourethral gland and rectum (with six patterns of branching) in males, and the vagina, clitoris and rectum (with three patterns of branching) in females.
对40只家兔（穴兔）的骨盆进行了双侧研究，采用体视显微镜下解剖和血管造影术。描述了骨盆的动脉模式，即脐动脉、泌尿生殖动脉和阴部内动脉（内脏分支）的起源和分支。观察到的主要特征如下：（1）脐动脉在成年家兔中是通畅的，发出膀胱颅侧动脉和一条尾侧分支，该尾侧分支为盆腔泌尿生殖器官供血，最终为直肠供血，在两性中均有六种分支模式。（2）通常，泌尿生殖动脉是髂内动脉内脏分支的延续。在1只动物中，单侧情况下，它起源于骶中动脉。在12只动物中（6只双侧缺失，6只单侧缺失），泌尿生殖动脉缺失。当存在时，它形成两个分支，一个颅侧分支和一个尾侧分支，为两性的泌尿生殖器官供血。（3）阴部内动脉是髂内动脉的直接延续，发出一些内脏分支，在雄性中为阴茎、尿道球腺和直肠供血（有六种分支模式），在雌性中为阴道、阴蒂和直肠供血（有三种分支模式）。
