Question

Match the LIST-I with LIST-II

• A. A-IV, B-III, C-I, D-II
• B. A-III, B-I, C-IV, D-II
• C. A-IV, B-I, C-III, D-II
• D. A-II, B-I, C-IV, D-III

Hint:

Endocrine Gland - Hormone Pairs:
Adrel Cortex = Cortisol.
Kidney = Erythropoietin (EPO).
Thyroid C-cells = Calcitonin.
Adrel Medulla = Epinephrine (Adreline).

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks to match endocrine glands or organs in LIST-I with their corresponding hormone secretions in LIST-II.

Step 2: Key Formula or Approach:
Match glands/organs with their primary hormone products:
• Adrel Cortex: Cortisol (Glucocorticoid from zo fasciculata).

• Kidney: Erythropoietin (EPO).

• Thyroid Gland: Calcitonin (from parafollicular C-cells).

• Adrel Medulla: Epinephrine (Adreline from chromaffin cells).

Step 3: Detailed Explation:

• A. Adrel cortex $\to$ IV. Cortisol: The zo fasciculata layer of the adrel cortex secretes cortisol in response to pituitary ACTH.

• B. Kidney $\to$ I. Erythropoietin: Interstitial fibroblasts in the kidney secrete erythropoietin (EPO) in response to hypoxia to stimulate red blood cell production in bone marrow.

• C. Thyroid $\to$ III. Calcitonin: Parafollicular cells (C-cells) of the thyroid gland produce calcitonin to lower blood calcium levels.

• D. Adrel medulla $\to$ II. Epinephrine: Chromaffin cells of the adrel medulla secrete catecholamines (epinephrine/adreline) during fight-or-flight sympathetic activation.

Step 4: Fil Answer:
The correct matching sequence is A-IV, B-I, C-III, D-II.
