The follicle that ruptures at the time of ovulation promptly fills with blood, forming:A: Corpus haemorrhagicum
B: Corpus luteum
C: Corpus albicans
D: Corpus callosum
Answer: a. Corpus haemorrhagicumDetailed When the follicle ruptures at the time of ovulation, it promptly fills with blood, forming a corpus haemorrhagicum. Here is a detailed explanation of the options:
A: Corpus haemorrhagicum:- This is the correct answer. After ovulation, when the follicle ruptures, it fills with blood, forming a corpus haemorrhagicum. This structure is temporary and is an early stage in the formation of the corpus luteum.
- The corpus haemorrhagicum is responsible for the release of hormones such as progesterone, which is essential for the preparation of the uterus for possible implantation of a fertilized egg.
B: Corpus luteum:- The corpus luteum is formed from the corpus haemorrhagicum. After the follicle ruptures and fills with blood, it undergoes changes and transforms into a corpus luteum.
- The corpus luteum produces hormones, primarily progesterone, which is important for the maintenance of a potential pregnancy.
C: Corpus albicans:- The corpus albicans is the final stage of the corpus luteum. If fertilization does not occur, the corpus luteum degenerates and forms a scar tissue called the corpus albicans.
- The corpus albicans is a non-functional structure and eventually gets reabsorbed by the body.
D: Corpus callosum:- The corpus callosum is a part of the brain that connects the left and right cerebral hemispheres. It is not related to the process of ovulation or the formation of the corpus haemorrhagicum.
In conclusion, the correct answer is A: Corpus haemorrhagicum, as it accurately describes the formation of the structure that fills with blood after follicle rupture during ovulation.
