Histological and Ultra Structure Observations of the Adrenal Gland of Fruit Eating Bat (Rousettus Aegyptiacus) | Biomedgrid

In Rousettus aegyptiacus, gland has two layers: cortex and medulla. Three layers of cortex distributed equally as seen with histological structure. Ultra-structural observations of the glomerulosa cells give mitochondria with vesicular cristae, a few lipid droplets and appear as large vacuoles, these droplets are variable in size, mainly round to ovoid in shape with an irregular boundary containing material of variable electron density and small vesicles of smooth endoplasmic reticulum scattered throughout the cytoplasm. Zona fasciculata is the major portion of the adrenal cortex, its cells are large and arranged in radial cords towards the medulla, it contain a greater number of lipid droplets than those observed in the cells of glomerulosa. Zona fasciculata cells have tubular profiles of smooth endoplasmic reticulum in the form of vesicles scattered throughout the cytoplasm. In contrast to the zona glomeruolosa the cells of the zona fasciculata are rich in smooth endoplasmic reticulum.
