Adrenal Histology - Cortex and Medulla

Adrenal gland, monkey - (Stain - Haematoxylin Eosin)

Adrenal Cortex - divided into three zones (Adrenocorticotropic hormone (ACTH) required for zones 2 and 3)

1. zona glomerulosa (about 15%)
2. zona fasciculata (about 75%)
3. zone reticularis is (about 10%)

Adrenal Medulla - 2 indistinguishable cell types, neural crest in origin.

1. Adrenaline producing cells - epinephrine (80%)
2. Noradrenaline producing cells - norepinephrine (20%)

• cells arranged in strands or small clusters with capillaries and venules in the intervening spaces.
• cell cytoplasm weakly basophilic.
  • chromaffin cells because granules can be stained with potassium bichromate.
• innervated by preganglionic sympathetic fibres.
