It releases two hormones called epinephrine and norepinephrine. Adrenal medulla is the internal or inner part of the adrenal gland. Adrenaline: Adrenal Medulla develops from Neuroectoderm of the embryo. Thyroid hormones also promote growth of body tissues-both physical growth and development of mental faculties are stimulated.Ĥ. Thyroxine: This is secreted from the thyroid gland. As the name suggests, these are the corticoids which are involved in carbohydrate metabolism.ģ. Cortisol: These are also the steroid hormones which are produced by the zona fasciculata layer of the adrenal cortex. These regulate the water and electrolyte balance in the body.Ģ. Aldosterone: These are the steroid hormones which are released from the zona glomerulosa layer of the adrenal cortex. Now let us gather information about given options :ġ. Zona glomerulosa: It is the outermost layer of the adrenal cortex. Zona fasciculata: It is the middle layer of the adrenal cortex. Zona reticularis: It is the innermost layer of the adrenal cortex. It is the external or outer part of the adrenal gland. These glands have dual origin i.e., from Mesoderm and Ectoderm of embryo Each adrenal gland is composed of two types of tissues, adrenal medulla and adrenal cortex.Īdrenal Cortex is derived from.

Each kidney has an adrenal gland on top of it.

These are paired glands located at the anterior part of the kidneys.

Hint: Adrenal glands also called suprarenal glands or glands of Emergency.
