Biology - Human Reproduction Question with Solution | TestHub
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Corpus luteum releases progesterone, small amount of estrogen and inhibin.
Reason (R): Under the influence of these hormones, the endometrial glands grow, become coiled and start uterine secretion.
In light of the above statements, choose thecorrectanswer from the options given below.
Options:
Answer:
Solution:
Assertion (A) states that the corpus luteum releases progesterone, a small amount of estrogen, and inhibin. This is a true statement, as the corpus luteum is primarily responsible for secreting large amounts of progesterone, along with some estrogen and inhibin, during the luteal phase of the menstrual cycle.
Reason (R) states that under the influence of these hormones, the endometrial glands grow, become coiled, and start uterine secretion. This is also a true statement, as progesterone and estrogen are responsible for maintaining the endometrium and inducing the secretory phase, which prepares the uterus for potential implantation.
However, Reason (R) describes the physiologicaleffector consequence of the hormones released by the corpus luteum, rather than explainingwhythe corpus luteum secretes them (which is primarily due to the influence of the Luteinizing Hormone (LH) surge). Since the Reason is an effect of the Assertion rather than its cause, (R) is NOT the correct explanation of (A).
Therefore, both (A) and (R) are true, but (R) is not the correct explanation of (A).
Answer: Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
