Abstract
Integumentary system of the polychaete, Perinezeis aibuhitensis was consisted cuticular, epidermal and dermal layers. Excretory pores opened in cuticular layer, which is covered with epicuticular projections. The hemidesmosomes were observed between supporting cell and basal area of cuticular layer. The epidermal layer was consisted supporting cells and unicellular glands. Supporting cell was relatively larger than the other neighbouring cells, and the nucleus had one to two nucleolus. Cytoplasm of the supporting cell had well-developed intracellular organs such as tonofilaments, mitochondria, rough endoplasmic reticula, free ribosomes and pigment granules of electron dense. The gland cells were reacted with blue in AB-PAS, and classified into the three types such as
두토막눈썹참갯지렁이의 피부계는 바깥쪽으로 부터 큐티클층, 상피층, 진피층으로 구성된다. 큐티클층은 외분비공을 가지며, 표면은 epicuticular projections로 덮여있다. 큐티클층과 상피층의 지지세포 사이에서는 반접착반이 관찰된다. 상피층에서는 지지세포와 선세포들이 관찰된다. 지지세포는 불규칙한 형태이며, 이들 세포의 핵은 뚜렷하고 크며,
