The adrenal medulla is not enclosed by a fibrous capsule, whereas a fibrous capsule encloses the adrenal cortex.

The adrenal medulla originates from the ectoderm, whereas the adrenal cortex originates from the mesoderm.

The adrenal medulla is soft, whereas the adrenal cortex is firm.

The adrenal medulla constitutes 25 per cent of the adrenal gland, whereas the adrenal cortex constitutes 75 per cent of it.

The adrenal medulla is the innermost part of the adrenal gland, whereas the adrenal cortex is the outermost layer that covers the adrenal medulla.

Main Differences Between Adrenal Medulla and Adrenal Cortex If any harm or destruction is caused, it may even lead to the death of the person. The adrenal cortex is an essential region that carries out several body processes. When a person undergoes stressful situations, this hormone helps increase the energy level and cope with stress. It also controls the rhythm of a person’s circadian. It is the hormone that makes use of fats, carbohydrates, and proteins in the body. This chemical regulates blood pressure, decreases bone formation, increases blood sugar, and reduces inflammation. They release chemicals when the sympathetic preganglionic neurons stimulate them.Īnother important hormone produced in the adrenal cortex is cortisol. The cells are also connected with the sympathetic division of the nervous system. These include adrenaline, noradrenaline, and a small amount of dopamine. It comprises chromaffin cells that are responsible for the secretion of hormones. The adrenal medulla is the soft region at the adrenal gland’s centre. The adrenal cortex is essential for life, and its destruction may prove to be fatal. The adrenal medulla is not essential for life, and its destruction does not cause death.

The major hormones the adrenal cortex releases include aldosterone, cortisol, and androgens. The major hormones released by the adrenal medulla include adrenaline and noradrenaline.

It develops or originates from the ectoderm. It constitutes 75 per cent of the adrenal gland. It constitutes 25 per cent of the adrenal gland. The adrenal cortex is the outermost layer of the adrenal gland. The adrenal medulla is the central or innermost part of the adrenal gland.
