It is made up of pale staining vacuolated cells arranged in parallel rows. Zona fasciculata is significantly thicker than the other two cortical layers.
Aldosterone regulates the uptake of water in the distal convoluted tubules, which consequently alters the body’s blood pressure. The zona glomerulosa is comprised of small rounded cells that are responsible for secreting mineralocorticoids such as aldosterone. The cortex can be subdivided into the zona glomerulosa, the zona fasciculata and the zona reticularis.
There is an outer fatty capsule just deep to the renal fascia that functions as an added protective layer.ĭeep to the capsule, is the suprarenal cortex.
However, only two of these layers are of homeostatic significance. Essentially the gland is divided into three layers.
