Question

Both corpus luteum and macula lutea are
A. Found in human ovaries
B. A source of hormones
C. Characterized by yellow colour
D. Contributory in maintaining pregnancy

Answer 1

Hint: The macula lutea is a region of the retina that is responsible for centre and detailed vision. A large number of cones can be found in the macula lutea. The follicular phase and the postovulatory or luteal phase are the two phases of a woman's menstrual cycle. The corpus luteum forms inside the ovary during this time.

Complete answer:
Option A: Under the influence of LH, the ovulated Graafian follicle differentiates into corpus luteum during the luteal phase of the ovarian cycle. As a result, the corpus luteum is present in the ovary.
The macula lutea is the centre part of the human retina, distinguished by the presence of cone cells in the fovea centralis.
So option A is not correct.
Option B: The corpus luteum secretes oestrogen, progesterone, and relaxin hormones, whereas the macula lutea does not.
So option B is incorrect.
Option C: In anatomy, the macula lutea is a tiny yellowish spot of the retina that gives central vision near the optic disc. The Corpus luteum, on the other hand, is made up of follicles that house mature eggs. Yellow lutein is found in both the corpus luteum and the macula lutea. It appears as a yellow spot on the skin.
So option C is correct.
Option D:If fertilisation is followed by implantation, the placental hormone human chorionic gonadotropin keeps the corpus luteum alive, allowing progesterone and estrogens to continue to be secreted. Because lower amounts of progesterone might lead to abortion or miscarriage owing to endometrial disintegration, the corpus luteum is required to keep a pregnancy going. The macula lutea is a retinal component that does not play a role in reproductive processes.
So option D is not correct.

So option C is the correct answer.

Note:
The Corpus luteum's main function is to pulse out hormones like progesterone. A viable pregnancy requires progesterone to start and persist. A high or low body mass index, intense exercise during the luteal phase, and other variables can all contribute to a corpus luteum shortage.
