Adrenal gland

The adrenal gland is situated on top of each one of the kidneys. They weigh 8-10g in weight and there is one on each side of each kidney. The Adrenal Gland produces a number of hormones such as epinephrine. There are three main areas of the adrenal gland, the Medulla, Cortex and Capsule. The capsule surrounds the adrenal gland and gives strength. The cortex can be seperated into three sections; the Zona glomerulosa, the Zona fasciculata and the Zona reticularis. The medulla is the site of synthesis of epinephrine and different zones of the cortex produce different steroids.
