Description
Summary:This paper presents the normal ultrastructural features of the androgenic gland in Porcellio scaber. It describes the changes in the organelles of its cells through the course of the secretory cycle, which terminates with the regression and destruction of these holocrine glandular cells. As products of this activity, the electron-opaque bodies (granules, lysosomes, agglomerates) and clear substances accumulate in the cytoplasm. With the destruction of the cell membrane, the entire cell content passes into the spaces of the haemocoele. The morphological modifications of the mitochondria and rough endoplasmic reticulum are the most striking changes.
