The venom glands are situated in the last segment of the metasoma, named the telson. The telson contains a pair of venom glands equal in size and shape. The two glands are segregated within the bulbous base of the telson by striated muscular bundles, and the outer surface of the venom glands is surrounded by a cuticle. An internal layer constitutes the secretory epithelium. This epithelium is made up of simple and columnar cells. The nucleus and organelles involved in synthetic activity of the cell are situated in the basal portion of the cells. In the apical portion of the cells near the gland lumen, there are many secretory granules of different sizes, shapes, and electron densities. All types of secretory materials are located in vesicles limited by the biomembranes.eninfo:eu-repo/semantics/closedAccessMesobuthus gibbosusscorpionvenom glandfine structureArticle613297306WOS:000273147700007N/A
