Verified step by step guidance
1
Understand the structure of the adrenal gland, which is divided into two main parts: the adrenal cortex and the adrenal medulla.
Recognize that the adrenal cortex is responsible for producing steroid hormones such as cortisol, aldosterone, and androgens. It is further divided into three zones: zona glomerulosa, zona fasciculata, and zona reticularis.
Identify the adrenal medulla as the inner region of the adrenal gland, which is responsible for producing catecholamines, including epinephrine (adrenaline) and norepinephrine (noradrenaline).
Note that the adrenal medulla functions as part of the sympathetic nervous system, releasing epinephrine and norepinephrine in response to stress.
Conclude that the adrenal medulla, not the adrenal cortex or its zones, is responsible for the production of epinephrine and norepinephrine.
