摘要
In this study, histological characteristics of the skin of adult lsa laying hens were observed. The results show that chicken skin is composed of epider- mis, dermis and hypodermis. The epidermis of chicken skin is thin, consisting of basal cells, spiny cells, transitional cells and horny cells. Specifically, there are few spiny cells scattered between the stratum basale and the transitional layer, without forming a layer; only 1 -2 layers of cells can be observed in the transitional layer. The derails is divided into superficial dermis and deep derufis. Moreover, deep dermis consists of dermal dense layer, dermal loose layer and elastic fibrous layer. There is no smooth muscle in pteryla within the dermal dense layer. The loose layer of deep dermis is developed, which is much much thicker than the dense layer. This study laid the foundation for in-depth investigation of the histological structure of poultry skin.
