WHAT IS THE ADRENAL GLANd
The adrenal glands are approximately two and half by one inch long yellowish-orange colored glands that are found just above the kidneys. Adrenal glands provide a very important function in protecting the body against stress. This function is carried out by secretion of a number of different types of hormones by the adrenal gland.
The adrenal gland is actually two glands that are fused together into one gland. The outer part of the adrenal gland also called the adrenal cortex produces steroid hormones that are involved in regulating a number of different body functions.
The adrenal cortex also produces a hormone called aldosterone that is involved in regulating the amount of salt and water in your body.
The inner part of the adrenal gland is called the adrenal medulla. The adrenal medulla produces hormones called catecholamines such as adrenaline and noradrenaline. Catecholamines play a role in the response to acute or sudden severe stress, for example during life threatening event.
Catecholamines are responsible for the palpitations (racing heart), sweatiness, widening of eyes and shakiness of the hand when faced with sudden fear or other stressful situation.
