Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Hydramnios is gradual progressive accumulation of fluid in amniotic sac
Reason R: Hypertrophy of endometrial glands leads to increased secretion of viscid and transparent fluid in the uterine lumen
In light of the above statements, choose the correct answer from the options given below

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Hint:

Remember the difference: hydramnios is a slow, gradual accumulation of amniotic fluid due to a defective fetus.
Hydroallantois is a rapid, sudden accumulation of allantoic fluid due to a diseased placenta (maternal/placental origin).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Hydroallantois and hydramnios are two distinct forms of dropsy (excessive fluid accumulation) affecting fetal membranes during gestation in domestic animals, particularly cattle.

Step 2: Detailed Explanation:
Let us analyze the physiological mechanisms behind these dropsical conditions:
- Assertion A: Hydramnios is a dropsy of the amnion.
It is characterized by a gradual, progressive accumulation of fluid in the amniotic sac over several months, usually resulting in a pear-shaped abdomen in the dam.
This is caused by a fetal abnormality (such as muscle contracture, head deformities, or brain defects) where the fetus fails to swallow and process amniotic fluid normally.
Therefore, Assertion A is correct.
- Reason R describes the hypertrophy of endometrial glands leading to increased secretion of viscid, transparent fluid in the uterine lumen.
This pathway describes uterine glandular hyperplasia or mucometra/hydrometra, not hydramnios.
Since hydramnios is a fetal-derived problem involving the failure of the fetus to swallow normal amniotic fluid, endometrial gland hypertrophy does not cause it.
Thus, Assertion A is true but Reason R is false.

Step 3: Final Answer:
The correct option is A is true but R is false.
