Ch. 11 Anatomy & Physiology of the Endocrine SystemAdrenal glandalso called suprarenal glandeither of two small triangular endocrine glands one of which is located above each kidney. In humans each adrenal gland weighs about 5 grams 0. Each gland consists of two parts: Prosteroids 2015 two parts differ in embryological origin, structure, and function. The adrenal glands vary in size, shape, and nerve supply in other animal species.

The adrenal glands are also called suprarenal glands. These are endocrine glands that lie like caps on top of the kidneys. In human beings the right adrenal gland is triangular shaped while the left suprarenal gland is shaped like half a moon or semilunar in shape. Each of the glands are around 4 to 6 cm in length. The outer part of the glands contains thick connective tissue capsule that sends thin fibers into the glandular tissues within.
The glandular part is called the parenchyma. The parenchyma is divided into two major parts:. The cortex secretes steroid hormones. These steroids are all derived from cholesterol.
Most of the cortex cells contain lipid inclusions or lipid portions. These lipids or fats are the basic molecules from which steroids are formed. The cells with their white fat globules appear like sponges and are thus called spongiocytes. The medulla secretes cathecholamines. The adrenal medulla has numerous capillaries and venules or thin arteries and veins. Since these cells stain brown when exposed to chromium salts they are called chromaffin cells. E and NE are cathecholamines that raise the heart rate, heart pumping capacity, blood pressure and rate of breathing.
The adrenal cortex secretes corticosteroids, such as glucocorticoids and mineralocorticoids. These hormones are responsible for responding to stress; using carbohydrates, fats and proteins; and regulating the salt and water balance in the body.
The adrenal medulla secretes both adrenalin and noradrenalin, also known as epinephrine and norepinephrine respectively. My Daughter is 24 years old her Adrenal Gland is not funnctioning properly and the endrocoloigst prescribed steroids.
Come to find her dose is to high. I have adrenal hyperplasia and am on 3mg prednisone daily. There is a great book 'Adrenal Fatigue'. It says to take Vitamin C tablets. Take the recommended amount 1st day and each day after add an extra one.
When you start getting 'the runs' decrease back to the dose before and that is how many your body needs. Keep taking that does until you feel more normal. Then you can decrease again. I have battled adrenal fatigue for years due to long term steroid use. I just wanted to say that I came across what looks to be promising for some help. He so makes sense.
