- Аннотация: The microscopical anatomy of the ovary of the articulate brachiopod Hemithyris psittacea was investigated by light and transmission electron microscopy. The ovary has a reticulate structure with connective tissue pillars, which pierce it. The pillars have a wine-glass form and consist of two parts — a column that is attached to inner mantle wall and a broader region that is attached to outer mantle wall. The coelomic epithelium of the column contains myofilaments orientated across the gonad cavity. The broader part contains parenchymal tissue with cells that are filled by the expanded profiles of rough endoplasmic reticulum. Globular cells with membrane-free inclusions were found in the mantle wall. The connective tissue pillars may prevent the collapse of gonad during gametogenesis and/or contract to facilitate spawning. It is assumed, that the parenchymal tissue and the globular cells take part in the nutrition of the oocytes and in the storage of the nutrients.
