The adrenal glands, also known as suprarenal glands, are small, triangular- shaped endocrine glands located on top of each kidney. They sit on the superomedial (upper inner) aspect of the kidneys, in the retroperitoneal space, just below the diaphragm

. The right adrenal gland is typically pyramidal in shape, while the left is more semilunar or crescent-shaped

. Each adrenal gland consists of two main parts: the outer adrenal cortex and the inner adrenal medulla, both producing different hormones essential for regulating metabolism, immune response, blood pressure, and stress response

. The glands are surrounded by a fatty capsule and enclosed within the renal fascia, which also surrounds the kidneys, attaching them to the diaphragm

. In summary, the adrenal glands are positioned directly atop the kidneys, nestled between the kidneys and the diaphragm in the posterior abdomen
