A comparative histological and histochemical study of the stomach from three species of pleuronectid, the Atlantic halibut, Hippoglossus hippoglossus, the yellowtail flounder, Pleuronectes ferruginea, and the winter flounder, Pleuronectes americanus

摘要: The morphology and the histochemistry of mucus pleuronectid stomach were examined using light electron microscopy. winter flounder (Pleuronectes americanus) yellowtail ferruginea) possessed a glandular or cardiac region an aglandular pyloric region, whereas Atlantic halibut (Hippoglossus hippoglossus) was entirely in nature. epithelia all three species could be divided into distinct zones based upon ultrastructural differences cell types present. Zone 1 contained surface mucus-secreting cells, zone 2 mucous neck 3 oxyntico-peptic cells gland cells. presence ultrastructurally is not consistent with observations teleost supports theory that gastric glands may exist without Variation across gastri...
