![]() On the other hand, adrenal medulla is the inner region of the adrenal gland, and it secretes amine hormones. What is the Difference Between Adrenal Cortex and Adrenal Medulla?Īdrenal cortex is the outer region of the adrenal gland, and it secretes steroid hormones. Cortex and medulla are two main parts of the adrenal gland.What are the Similarities Between Adrenal Cortex and Adrenal Medulla? Zona reticularis is the innermost layer, and it occupies about 10% of the cortex. Zona fasiculata is the middle layer, and it is the major portion of the adrenal cortex and occupies 80% of the cortex. Zona glomerulosa is the outermost layer which occupies 10% of the cortex area. Side by Side Comparison – Adrenal Cortex vs Adrenal Medulla in Tabular FormĪdrenal cortex is the outer region of the adrenal gland. Adrenal cortex produces steroid hormones whereas adrenal medulla produces epinephrine and norepinephrine. Adrenal cortex is the outer region of the adrenal gland while adrenal medulla is the inner region of the adrenal gland. ![]() Adrenal gland has two main parts: adrenal cortex and adrenal medulla. They are endocrine glands, which secrete different hormones. Therefore, there are two adrenal glands in humans. The key difference between adrenal cortex and adrenal medulla is that adrenal cortex is the outer region of the adrenal gland that secretes steroid hormones while adrenal medulla is the centre of the adrenal gland that secretes epinephrine and norepinephrine.Īdrenal gland is a small triangular organ located just above the kidney. ![]()
