Adrenal Histology - Cortex and Medulla

Adrenal gland, monkey - (Stain - Haematoxylin Eosin)

Capsule - a fibrous capsule.

  • surface of the gland is surrounded by fat tissue.
  • vessels enter the organ through the furrows on its anterior surface and base.
  • arteries from the aorta,inferior phrenic, and the renal
  • arteries are numerous and relatively large size, subdivide into branches entering the cortical part of the gland
  • break up into capillaries ending in the venous plexus of the medullary portion.

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.
