Question

Match List-I with List-II.

List-I	List-II
A. Excess growth hormone	I. Reabsorption of water and electrolytes in kidney
B. Luteinizing hormone	II. Contraction of uterus during child birth
C. Vasopressin	III. Acromegaly
D. Oxytocin	IV. Ovulation

Choose the correct answer from the options given below :

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

Hint:

Acromegaly is hard to diagnose in its early stages because the anatomical changes occur very slowly over time. Oxytocin acts on a positive feedback loop during labor, increasing contraction intensity as labor progresses.

Answer 1

The Correct Option is C

Concept:

• Growth Hormone (GH): Hypersecretion of GH in adults causes

Acromegaly, characterized by the disproportional enlargement of bones in the face, hands, and feet.

• Luteinizing Hormone (LH): A pituitary gonadotropin that stimulates follicle maturation and triggers

ovulation of the mature Graafian follicle.

• Vasopressin (Antidiuretic Hormone - ADH): Enhances water and electrolyte permeability in the distal tubules and collecting ducts of

kidneys, facilitating reabsorption.

• Oxytocin: Acts on smooth muscle tissues, causing strong

uterine contractions during childbirth (parturition).

Step 1: Match hormone items between List-I and List-II
A. Excess growth hormone \(\rightarrow\)

III. Acromegaly
B. Luteinizing hormone \(\rightarrow\)

IV. Ovulation
C. Vasopressin \(\rightarrow\)

I. Reabsorption of water and electrolytes in kidney
D. Oxytocin \(\rightarrow\)

II. Contraction of uterus during child birth

Step 2: Select the corresponding correct option
The matching sequence is A-III, B-IV, C-I, D-II, which corresponds to option (3).
