Verified step by step guidance

Understand the function of the adrenal medulla: The adrenal medulla is part of the adrenal glands, located on top of the kidneys. It plays a crucial role in the body's response to stress by releasing specific hormones.

Identify the hormones produced by the adrenal medulla: The adrenal medulla primarily secretes catecholamines, which include epinephrine (adrenaline) and norepinephrine (noradrenaline). These hormones are involved in the 'fight or flight' response.

Differentiate between the adrenal cortex and adrenal medulla: The adrenal cortex, another part of the adrenal glands, produces different hormones such as aldosterone and cortisol. These hormones are involved in regulating metabolism and electrolyte balance.

Recognize the role of epinephrine: Epinephrine is a hormone that increases heart rate, muscle strength, blood pressure, and sugar metabolism. It prepares the body to respond to stress or danger.

Conclude that epinephrine is the hormone released by the adrenal medulla, distinguishing it from hormones like aldosterone and cortisol, which are produced by the adrenal cortex.
