![]() The individual layers are called the zona glomerulosa, zona fasciculata and zona reticularis. According to the arrangement of the trabeculae, the adrenal cortex is divided into three concentric layers, which in man are not precisely delimited. The cells of the adrenal cortex do not accumulate secretory products in granules. The cells of the adrenal cortex have the characteristics of steroid-secreting cells they have a spherical, centrally placed nucleus, in the cytoplasm we can find a massively developed smooth endoplasmic reticulum, numerous mitochondria of tubular type and lipid droplets. ![]() ![]() The cells here are arranged in trabeculae surrounded by blood sinusoids. Schematic of cellular organization in the adrenal gland From this sheath, a septa containing weak arteries lead into the gland. The gland is embedded in a connective sheath (capsula fibrosa) that sits firmly against the organ surface. The right adrenal gland is triangular in shape, the left is crescentic. On the gland we recognize the facies anterior, facies posterior and facies renalis (renal surface). Dorsally the adrenal glands insist on the diaphragm, ventrally the liver is in front of the right adrenal gland and the pancreas and stomach in front of the left. Due to the lower position of the right kidney, the right adrenal gland is also located lower. ![]() The adrenal glands are located retroperitoneally at the upper poles of the kidneys at the level of Th11. ![]()
