摘要
对胎生蜥Lacerta vivipara的排泄和生殖系统进行了解剖观察。胎生蜥的排泄系统由肾脏、输尿管和泄殖腔组成,左肾较右肾稍大,但在位置上没有明显差别;雄性生殖系统由精巢、输精管、附睾和半阴茎组成,左侧精巢位置较右侧稍接近身体前部且稍大;雌性生殖系统由卵巢和输卵管组成,左右卵巢在大小上无明显差别,但左侧卵巢比右侧卵巢略接近身体前部。对繁殖期和繁殖期后的生殖系统比较显示,生殖腺在繁殖期明显增大。胎生蜥的生殖系统与其他卵生和卵胎生类蜥蜴无明显差别。
Observation and dissection of the urogenital system of an adult Laeerta vivipara was conducted. The results showed that ： the excretory system was composed of kidney, ureter and cloaca, the kidney on the left side of the body was bigger than the one on the right side ; the reproductive system of adult male L. vivipara was composed of the testis, sperma- duct, epididymis, and hemipenis; the left spermary of the male was bigger and slightly closer to the head than the right spermary. The reproductive system of the adult female was composed of an ovary and oviduct. The size of the ovary, on the left side of the body was the same as the one on the right side, whereas the left ovary was higher than the right one. During the reproductive period, the L. vivipara＇s sex gland became obviously larger than the same sex gland after the reproductive period. Besides, the reproductive system of L. vivipara was similar to these of other oviparous and ovoviviparous lizards.
