The adrenal glands are located on both sides of the body in the retroperitoneum, above and slightly medial to the kidneys. In humans, the right adrenal gland is pyramidal in shape, whereas the left is semilunar or crescent shaped and somewhat larger. [8] The adrenal glands measure approximately 5 cm in length, 3 cm in width, and up to 1 cm in ...
Adrenal medulla. The adrenal medulla (Latin: medulla glandulae suprarenalis) is the inner part of the adrenal gland. [1] It is located at the center of the gland, being surrounded by the adrenal cortex. [1] It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines, including epinephrine ...
The adrenal arteries are arteries in the human abdomen that supply blood to the adrenal glands. The adrenal glands receive input from three different arteries on both the left and right sides of the body: superior suprarenal artery branching from the inferior phrenic artery. middle suprarenal artery branching from the abdominal aorta.
The superior suprarenal artery is a branch of the inferior phrenic artery. [1] There may be multiple branches, each of which is fairly small. [1] The inferior phrenic artery is itself is a branch of the aorta. [1] The phrenic artery supplies the diaphragm.
Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals.These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the regulation of blood pressure.

Each vessel gives off some small inferior suprarenal branches to the suprarenal gland, the ureter, and the surrounding cellular tissue and muscles. One or two accessory renal arteries are frequently found, especially on the left side since they usually arise from the aorta, and may come off above (more common) or below the main artery.
Middle suprarenal arteries. The middle suprarenal artery ( middle capsular artery) is a paired artery in the abdomen. It is a branch of the aorta. It supplies the adrenal gland .
Adrenal gland disorder. Depiction of location of adrenal glands in human body. Specialty. Endocrinology. Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [ 1 ] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction.
