Abstract:
The present investigation was carried out on 12 pairs of adrenal glands from recently slaughtered pigs of both genders of 6-12 months age group. Histologically, the adrenals were divided in stroma and parenchyma. Stroma consisted of capsule and trabeculae. Collagen and reticular fibres were present at the capsule. Parenchyma composed of the cortex and medulla. Cortex was divided into three portions according to their cell arrangements in zona glomerulosa, zona fasciculata and zona reticularis. Reticular fibres were present throughout frame work of the adrenal glands. The Medulla was divided in the inner and outer parts. Inner medulla had polyhedral cells where as outer medulla had columnar shaped cells. Collagen fibres were also present at the medullary area. Patches of medulla were seen at some cortex area.
