Correct Answer: C
Explanation:
The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a wide variety of hormones. They are found on the top of the kidneys and consist of a number of different layers that directly influence the structure and function of the glands. Each gland has an outer cortex made of steroid-producing cells surrounding a core of medulla, formed by chromaffin cells in direct relationship with the sympathetic nervous system. The adrenal cortex is divided into three zones according to their functions and microscopic appearance.
