Histological Study of Adrenal Gland of One Humped Camel (Camelus dromedarius)

The investigation was carried out on the adrenal glands of 6 recently dead adult camels. Histologically, the adrenals were divided into stroma and parenchyma. Stroma consisted of capsule and trabeculae. Collagen and reticular fibres were present at the capsule and trabeculae. Parenchyma was composed of the cortex and medulla. The cortex was divided into three parts according to their cell arrangement: zona glomerulosa, zona fasciculata, and zona reticularis. The trabeculae entered into the cortex at various distances. The medulla was divided into the inner and outer parts. The outer zone was lined by columnar-shaped cells, and the inner area had polyhedral cells. Patches of the medulla were seen in some cortical areas. The adrenal gland of the camel was surrounded by a thick layer of dense connective tissue fibres, specially collagen and reticular predominance over the elastic and muscle fibres.
