Question

When the egg is not fertilized, the yellow-colored corpus luteum degenerates to form
a. Corpus Albicans
b. Corpus callosum
c. Corpus bigemina
d. Corpus quadrigemina

Answer 1

If the egg isn't prepared or doesn't embed, the lady's body sheds the egg and the endometrium. This shedding causes seeping in a lady's feminine period. At the point when a treated egg embeds, a hormone called human chorionic gonadotropin (hCG) starts to be delivered in the uterus.

Complete answer:

The Corpus luteum is otherwise called the yellow emitting body which is answerable for the emission of progesterone. Progesterone is significant for looking after pregnancy. On the off chance that the egg isn't treated, at that point, the Corpus luteum has deteriorated and it structures Corpus Albicans. It takes around 10 days for the degeneration of the Corpus luteum and it is available as a mass fiber of scar tissue. In this way, the right alternative is 'Corpus Albicans'

The corpus callosum is an enormous, C-molded nerve fiber group found underneath the cerebral cortex. It extends over the midline of the cerebrum, interfacing the left and right cerebral sides of the equator. It makes up the biggest assortment of white issue tissue found in the cerebrum. So, option B is incorrect.

The corpus quadrigemina in warm-blooded creatures are four strong projections on the dorsal side of the cerebral reservoir conduit, where the predominant back pair are called the unrivaled colliculi and the mediocre back pair is known as the second rate colliculi. The four-strong flaps help to decussate a few filaments of the optic nerve. So, option D is incorrect

Corpus bigemina of fishes, batrachians, and winged creatures are homologous with the corpora quadrigemina of vertebrates. So, option C is incorrect.

Hence, the correct answer is option (A).

Note: The corpus Albicans (Latin for "brightening body"; otherwise called atretic corpus luteum, corpus candicans, or essentially as Albicans) is the relapsed type of the corpus luteum. As the corpus luteum is being separated by macrophages, fibroblasts set down sort I collagen, framing the corpus Albicans. The respective single expanding of the roof plate of the undeveloped midbrain that later being developed becomes partitioned into a predominant and a sub-par colliculus.
