Histological SStudy On Venom Gland Apparatus In Odontobuthus doriae (Scorpions:Buthidae), Scorpio maurus Towsendi (Scorpiones:Scorpionidea) And Hemiscorpius lepturus (Scorpions:Hemiscorpidea) From Iran

Histological investigations were carried out on the venom gland of Hemiscorpius lepturus, Scorpio maurus townsendi, Odontobuthus doriae. The results revealed that the walls of H.lepturus poison sacs were single folded whereas those of both S. m. townsendi and O. doriae were complex folded. The number of folds O.doriae was higher than S. m. townsendi. It is notable that in O. doriae, there were two groups of cells in the poison sac. The venom-producing cells were visible on one side and the mucosal cells on the other side. The mucus cells observed by Masson trichrome staining were darker at the base of the cell than the apex.
