Questions: Which la a the adremal gland secretes a non-steroidal hormone? Zonal glomerulosa Zona fasciculata Medulla Zona reticularis

The answer is the third one: Medulla.

Explanation for each option:

• Zona glomerulosa: This part of the adrenal cortex secretes mineralocorticoids, such as aldosterone, which are steroid hormones. Therefore, it does not secrete a non-steroidal hormone.

• Zona fasciculata: This part of the adrenal cortex secretes glucocorticoids, such as cortisol, which are also steroid hormones. Thus, it does not secrete a non-steroidal hormone.

• Medulla: The adrenal medulla secretes catecholamines, such as adrenaline (epinephrine) and noradrenaline (norepinephrine), which are non-steroidal hormones. Therefore, this is the correct answer.

• Zona reticularis: This part of the adrenal cortex secretes androgens, which are steroid hormones. Hence, it does not secrete a non-steroidal hormone.

In summary, the adrenal medulla is the part of the adrenal gland that secretes non-steroidal hormones.
