Arterial vascularization of the penis in the chinchilla (Chinchilla lanigera)

Penis'in arteriyel vaskularizasyonu 10 sağlıklı, ergin erkek şinşilla kullanılarak çalışıldı. Arteria carotis communis'ten kırmızı mürekkep ile renklendirilmiş latex enjekte edilerek, lup altında diseksiyon yapılıp arteriyel vaskularizasyonu ortaya çıkarıldı. Şinşillada penisin esas kan damarımn arteria pudenda interna'dan gelen arteria penis olduğu gözlendi. Arteria penis arcus ischiadicus'tan 4-5 mm önce üç kola ayrıldı. Bunlar arteria profunda penis, arteria dorsalis penis ve en ince dal'dır (urethhra'yı girer ve besler). Penis'in diğer arterleri arteria pudenda externa'dan çıkar ve iki kola ayrıldı. Bu kollardan biri preputium'a uzanmış ve diğer kol ikiye ayrılmıştır. Bu kollardan biri musculus ischiocavernosus, rectum ve çevresindeki kaslara, diğer kolda penis'in kök kısmına girdiği belirlendi.

Şinşilla' da (Chinchilla lanigera) Penis' in arteriyel damarlaşması

The arterial vasculature of the penis was studied in a total of 10 apparently healthy adult male chinchillas. In order to exhibit the arterial vascularization network by dissecting under a magnifier, latex colored with red ink was injected through the carotic common artery. The main vessel of the penile blood supply in the chinchilla was observed to be penile artery. It was determined to be a branch coming from the internal pudendal artery. The penile artery was divided into three branches before 4-5 mm from the ischiadic arc. These were the deep artery of the penis, the dorsal penile artery and the most thin branch (entered and supplied the urethrae). The other penile arteries arised from the arteria pudenda externa and divided into two branches. One of these branches extended to preaputium and the other also divided into two further branches. The one branch supplied blood to the ischiocavernosus muscle, rectum and surrounding muscles and the remaining branch extented up to the root of the penis.
