| 摘 要： | 为探索羊驼易发尿道阻塞而致膀胱破裂的形态学特征,采用大体解剖学和普通石蜡切片技术,对雄性羊驼的尿生殖道和阴茎进行了研究,并与反刍动物的相关结构进行了比较。结果表明,雄性羊驼的尿生殖道分骨盆部和阴茎部,阴茎部靠近皮下,且背侧与骨性骨盆联合紧贴,外伤和出血均易导致阻塞;阴茎在阴囊后形成乙状弯曲。组织学发现尿生殖道骨盆部黏膜为变移上皮,阴茎部海绵体和阴茎海绵体结构相似,阴茎头末端皮下有一层软骨组织。

| Abstract: | In order to researth morphological feature of urethral obstruction lead to vesical rupture, the urethra and penis of male alpacas were studied by macroscopic anatomy and paraffin section, and compared with that of ruminants. The results showed that the urethra in the male alpaca were divided into pelvic portion and penis portion, the penis of urethra were close to subcutaneous, and clingy to osseous symphysis pelvis, so both trauma and hemorrhage lead to urethral obstruction; the penis formed a sigmoid flex... |
