In the present study, the distributional pattern of the penile artery and the vessels joining the blood supply of the penis were investigated in the New Zealand rabbit. Eight adult rabbits were used in the study. In order to exhibit the vascular network by dissection, latex was injected via the abdominal aorta. The main vessel which supplies blood to the penis, the penile artery, is a branch of the internal pudendal artery. It divides into two branches which form the deep and dorsal penile arteries at the level of the ischiadic arch. The deep penile artery penetrates the tunica albuginea, and forms the arterial network of corpus cavernosum penis. On the other hand, the dorsal penile artery gives off three small branches for the subischiocavernosus muscle and at the level of the attachment of this muscle sends two small branches for the preputium. The course of both arteries follows the dorsolateral surface of the penis to the glans and ends in an anastomosis. Hence, a caudal branch of the prostatic artery which originates from the umbilical artery joins the blood supply of the penis in the rabbit. After vascularizing the prostate complex, it ends by entering the corpus spongiosus penis at the dorsolateral surface at the level of the ischiadic arch.
在本研究中，对新西兰兔阴茎动脉及连接阴茎血供的血管分布模式进行了研究。研究使用了8只成年兔。为通过解剖展示血管网络，经腹主动脉注入乳胶。供应阴茎血液的主要血管即阴茎动脉，是阴部内动脉的一个分支。它在坐骨弓水平分为两个分支，形成阴茎深动脉和阴茎背动脉。阴茎深动脉穿入白膜，形成阴茎海绵体动脉网。另一方面，阴茎背动脉为坐骨海绵体肌发出三个小分支，并在该肌肉附着水平为包皮发出两个小分支。两条动脉均沿阴茎背外侧表面走行至龟头，并在吻合处终止。因此，源自脐动脉的前列腺动脉的一个尾侧分支在兔中汇入阴茎血供。在使前列腺复合体血管化后，它在坐骨弓水平的背外侧表面进入阴茎海绵体并终止。
