The zona glomerulosa, the outer zone, is responsible for the secretion of mineralocorticoid hormones. The cortex is divided into three layers or zones. Whereas a dog could survive the surgical excision of his adrenal medulla, the adrenal cortex is essential to life. Norepinephrine’s primary action is to increase blood pressure. The second hormone produced by the adrenal medulla is norepinephrine, also known as noradrenaline. It increases the heart rate and force of heart contractions, facilitates blood flow to the muscles and brain, decreases stomach and intestinal activity, and helps with conversion of glycogen to glucose in the liver – all actions that would promote a lifesaving fight or flight. The first, epinephrine (commonly known as adrenaline), plays a central role in short-term stress reactions.

The center of the adrenal gland, the adrenal medulla, produces two important hormones that are secreted in times of acute and severe stress, in what is known as the “fight or flight” mechanism. These two areas are entirely different in their function, their cellular structure, and their embryological origin, so it’s odd (at least in terms of our current understanding of the complex gland) that they are “built” into the same structure.

The adrenals consist of two distinct parts: the outer cortex and the inner medulla. They also help regulate body processes such as digestion, the immune system, and energy usage. Their joint activities help control the body’s reactions to stress, whether it is physical or psychological. The adrenal glands also interact with the hypothalamus and pituitary gland the collaboration of the three glands is known as the hypothalamic-pituitary-adrenal axis (HPA axis). Although small in size, they are extremely important in the overall hormonal balance of the body and its ability to maintain homeostasis. They are so small, in fact, they were virtually ignored by early anatomists for centuries. The adrenals are small glands located just forward of the kidneys. The herb’s activity actually helps balance the adrenals. Give licorice root to any dog with Addison’s disease or adrenal fatigue. Steroidal drugs are a prime cause of Cushing’s disease.ģ. Avoid giving your dog corticosteroids for chronic conditions or long-term use. If symptoms such as hair loss, lethargy, weight loss, and sudden onset of excessive thirst and urination are seen, get the dog to your vet ASAP.Ģ.
