Adrenal Cortex: 3 Layers Exam Questions and
answers
three layers of Adrenal cortex - ✅✅Zona Glomerulosa
Zona Fasciculata
Zona Reticularis
Zona Reticularis - ✅✅Innermost layer of the cortex
Produces adrenal sex hormones
Most are androgens that are converted to testosterone in tissue cells or estrogens in females
Zona Fasciculata - ✅✅Middle zone of the cortex
Zona Glomerulosa - ✅✅Most superficial layer of the cortex
Zona Glomerulosa - ✅✅Produce mineralocorticoids
Zona Glomerulosa - ✅✅Regulates electrolytes/minerals, Na+ and K+ in extracellular fluid
Zona Glomerulosa - ✅✅Na+: most important cation in the ECF
Where Na+ travels, so goes water
Changes in Na+ concentration impacts changes in blood volume/pressure
Zona Glomerulosa - ✅✅Most potent mineralocorticoid: aldosterone
Zona Glomerulosa - ✅✅K+: sets RMP of cells
Zona Glomerulosa - ✅✅Determines ease of AP generation threshold
