The adrenal glands are a pair of organs above the kidneys which produce hormones. The outer covering is called the adrenal cortex and is comprised of three layers: the zona glomerulosa, the zona fasciculata and the zona reticularis. The inner core...
The adrenal glands are made up of two different parts: the medulla (inner portion) and the cortex (outer portion). The adrenal medulla is responsible for making the two catecholamine hormones, which are epinephrine and norepinephrine. These two...
The two adrenal glands are also called the suprarenal glands, because each sits on top of a kidney. The glands are organized into different sections, each of which is responsible for making substances that affect various functions within the body....
The adrenal glands are two small organs located on top of each kidney, and they each consist of two main regions--the adrenal medulla and the adrenal cortex. The adrenal medulla produces the catecholamines epinephrine (adrenaline) and...
Addison's disease is primarily an autoimmune disease whereby the immune system attacks the adrenal glands, which sit on top of the kidneys. As a result of a decrease in the hormones released by the adrenal glands, the kidneys hold onto potassium....
There is one adrenal gland on top of each kidney. The gland is made of two parts. The adrenal medulla is the inner part of the gland. The adrenal cortex is the outer part. It makes up 90 percent of the gland and has three areas which are referred...
An adrenal gland is found on the upper edge of each kidney, where it is attached to the kidney. Composed of two parts, the inner part of the gland is called the adrenal medulla. The outer part is the adrenal cortex. There are three areas, or...
The adrenal glands, also known as the suprarenal glands, are part of the endocrine system. The endocrine system produces hormones, substances that regulate the activity of body organs and tissues. Beginning in the womb, the adrenal glands produce...
The adrenal glands sit just above the kidneys. Their function is to make hormones crucial for life. There are two major areas of each adrenal gland: the outer cortex and inner medulla. The cortex is further subdivided into a zona glomerulosa, zona...
The adrenal glands lie atop the kidneys and produce several different types of hormones. The inner core, or medulla, of the adrenal glands produces "stress hormones" like epinephrine--adrenaline--while the outer layer or cortex produces androgens,...
The correlation between hand exercises and lowered blood pressure was established quite by chance in the late 1960s, when doctors were studying the health problems of pilots performing G-force maneuvers in the U.S. Air Force new F-16 aircraft. ...
