In the following diagram, which of the following hormones is produced in zone of the adrenal gland labeled as D?
Glucocorticoids
Mineralocorticoids
Catecholamines
Androgens
Epinephrine
The Correct Answer is A
a) Glucocorticoids: The zona fasciculata is the middle layer of the adrenal cortex. It primarily secretes glucocorticoids, mainly cortisol, which helps regulate metabolism, immune response, and stress adaptation.
b) Mineralocorticoids: Mineralocorticoids like aldosterone are produced in the zona glomerulosa, the outermost layer of the adrenal cortex.
c) Catecholamines: Catecholamines (e.g., epinephrine and norepinephrine) are produced in the adrenal medulla, not the cortex.
d) Androgens: Androgens (e.g., DHEA) are produced in the zona reticularis, the innermost layer of the adrenal cortex.
e) Epinephrine: Epinephrine is a catecholamine produced in the adrenal medulla. It is not produced in any zone of the adrenal cortex, including the zona fasciculata.

c) Hemosiderosis: This is a pathological condition caused by excess iron deposition in tissues, not a normal storage mechanism.
d) Ferrin: “Ferrin” is not a physiologically recognized iron storage molecule.
Correct Answer is C
Explanation
a) B negative: If the patient had B negative blood: There would be agglutination with Anti-B,No agglutination with Anti-A or Anti-D.
b) AB positive: AB positive means agglutination with: Anti-A, Anti-B, and Anti-D.
c) A positive: Agglutination with Anti-A means the red cells have A antigens. No agglutination with Anti-B means B antigens are absent. Agglutination with Anti-D indicates the Rh factor is present, making the blood type Rh positive.
d) O negative: O negative blood has no A, B, or Rh antigens, so there would be: No agglutination with Anti-A, No agglutination with Anti-B, and No agglutination with Anti-D.
