Adrenal Histology - Cortex and Medulla
Adrenal Cortex - divided into three zones (Adrenocorticotropic hormone (ACTH) required for zones 2 and 3)
- zona glomerulosa (about 15%)
- zona fasciculata (about 75%)
- zone reticularis is (about 10%)
Adrenal Medulla - 2 indistinguishable cell types, neural crest in origin.
- 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.
Cells
- Adrenaline producing cells - epinephrine (80%)
- Noradrenaline producing cells - norepinephrine (20%)
