Abstract
The ultrastructure of adrenal gland of guinea fowl was recorded by using scanning and
transmission electron microscopy. The parenchyma of adrenal gland constituted mainly of three
components, namely cortical or interrenal tissue, medullary or chromaffin tissue and vascular
sinusoids. Four types of cells viz., type-I, II, III and IV were identified in adrenal cortex by
transmission electron microscopy. In scanning electron microscopy the cortical cells showed
blebs, cords, globules and cord like aggregates on their surface. In transmission electron
microscopical observation, three types of cells were identified in medullary tissue of adrenal
gland viz., Adrenaline cells, nor adrenaline cells and stellate shaped satellite cells. In scanning
electron microscopical observation, the medullary cells were granular filamentous structure
and showed prominent microvillus like projection on their surface.
