Electron Microscopic Studies on the Adrenal Gland of Hipposiderid Male Bat, Hipposideros lankadiva

Adrenocortical and medullary zones are distinct in Hipposideros lankadiva. The cortex is further differentiated into three distinct zones-zona glomerulosa, fasciculata and zona reticularis. The cells of zona glomerulosa are polyhedral and are arranged in the form of acini or group of cells. Mitochondria are rod shaped with lamelliform or tubular cristae and are randomly distributed in the cytoplasm. Golgi apparatus is indistinct. Profiles of rough endoplasmic reticulum are scarce. Few profiles of vesicular agranular endoplasmic reticulum are observed. Few lipid droplets and lysosomes are also encountered in the cytoplasm.
