Abstract
The cycle of the seminiferous epithelium and morphological features of spermatids in Crocidura dsinezumi were studied by light microscopy. The cycle of the seminiferous epithelium was divided into 12 stages. The dark type of spermatogonium(Ad) is appeared in all stages, and intermediate(In) in stage IV and B spermatogonium in stage V and VI were observed. The development of the acrosomal system, and changes in nuclear morphology of spermatids were divided into 14 steps. The Golgi, cap, acrosomal, maturation and spermiation phases were observed during steps
제주땃쥐(Crocidura dsinezumi)의 세정관 상피 주기와 정자세포의 형태적인 특징을 알아보기 위하여 조사하였다. 제주땃쥐의 세정관 상피 주기는 12 stages로 구분되어졌다. Ad형 정원세포는 모든 단계에서 관찰되어졌으며, In형 정원세포는 IV단계에서, B형 정원세포는 V단계와 VI단계에서 관찰되었다. 정자세포의 첨체 발달과 핵의 형태적 변화는 14 steps로 구분되어졌다. 골지, 두모, 첨체, 성숙 및 이탈단계는 각각
