アカニシの中腸腺と唾液腺の構造 Strucrure of digestive diverticula and salivary gland of the Thomas's rapa whelk, Rapana venosa (gastropoda : neogastropoda) Yamamoto, Ken-ichi 山元, 憲一 ヤマモト, ケンイチ Yamamoto 山元 ヤマモト Ken-ichi 憲一 ケンイチ 40416467 Handa, Takeshi 半田, 岳志 ハンダ, タケシ Handa 半田 ハンダ Takeshi 岳志 タケシ 70399666 Kondo, Masakazu 近藤, 昌和 コンドウ, マサカズ Kondo 近藤 コンドウ Masakazu 昌和 マサカズ open access Thomas;s rapa whelk; corrosion cast; digestive diverticula; salivary gland The structure of the digestive diverticula of the Thomas's rapa whelk, Rapana venosa, was examined with corrosion casts and histological structures. The cast was made using the prepolymerization methyl methacrylate (MercoxCL- 2 R) containing 10 % Mercox MA. Two ducts of the digestive diverticula came out of one embayment of the stomach. In dividing into the secondary duct from the main duct, it has been connected with each tubule. In short, the digestive diverticula of the whelk showed the simple branching type. The inside of their ducts was being covered with the cilium. The tubule composed of the digestive cell (cell dyed in the blue with Azan staining), and developed cilium. Both forms and size of the salivary gland were similar to them of the digestive diverticula, when the gland was observed in the mold. However, it showed the monopodial branching type. One duct of the salivary gland came out of one orifice of the oesophagus near mouth and covered with the cilium. 水産大学校 National Fisheries University 2007-03-15 jpn departmental bulletin paper https://fra.repo.nii.ac.jp/records/2011847 fishu_k_55_101 https://agriknowledge.affrc.go.jp/RN/2010750323 agriknowledge AN00124678 0370-9361 水産大学校研究報告 Journal of National Fisheries University 55 3 14 101 114 https://fra.repo.nii.ac.jp/record/2011847/files/fishu_k_55_101.pdf application/pdf 6.0 MB 2024-10-11
