In this way, the adrenal medulla and the sympathetic nerves support each other and can act as substitutes for each other. Their production and distribution by the blood usually occur at the same time that the organs are being stimulated by the sympathetic nerves. These hormones enter the blood stream and are carried throughout the body where they indirectly act as stimulants to the various organs.
It releases the hormones epinephrine and norepinephrine in response to stimulation of the sympathetic nervous system. This is actually a glandular extension of sympathetic effector fibers or postganglionic neurons. Call (212) 305-0444 or request an appointment online.Adrenal Medulla. If you are dealing with an adrenal issue, our team at the Columbia Adrenal Center is here to help. The following sections will provide information about adrenal conditions and their symptoms, diagnosis, treatment, and, where applicable, what is known about genetic causes. linked to specific genes or syndromes), most of the time they are sporadic or random. While some adrenal diseases can be inherited (i.e. The early detection and treatment of adrenal disease can significantly improve outcomes and profoundly improve a patient's quality of life. The main diseases of a hyperactive adrenal gland include: primary hyperaldosteronism (too much aldosterone), Cushing's syndrome (too much cortisol), and pheochromocytoma/paraganglioma (too much adrenaline). helps you respond to stressful situations) and are better known as& adrenaline.Īdrenal disease usually occurs when there is a tumor (either cancer or benign) and/or a hyperactive adrenal gland that makes too much of any of these hormones. These hormones help with the 'fight or flight' response (i.e. The adrenal medulla, or inner portion of the adrenal gland, produces a group of hormones known as catecholamines.
Hormone: Sex hormones (testosterone, estrogen)įunction: Control reproductive organs and development of male/female characteristics
The adrenal cortex, or outer portion of the adrenal gland has three layers, each making a different hormone:įunction: Controls immune system, inflammation, stress response If the adrenal gland were a peanut butter sandwich, the cortex would be the bread and the medulla the peanut butter. The glands consist of an outer part called the cortex and an inner part called the medulla. The adrenal glands make a variety of hormones that are essential to maintaining the normal function of the body. The adrenal glands are two small glands (each weighs about 4 to 6 grams) located in the back of the abdomen immediately above the kidneys.
