46. Given the following image, which endocrine structure is formed from the luteinization of the collapsed follicle?
Answer: C
Corpus luteum
The structure formed from the luteinization of the collapsed follicle is the corpus luteum. This temporary endocrine gland plays a crucial role in maintaining pregnancy by producing hormones, particularly progesterone.
A) Corpus primary
The corpus primary is not a recognized term in the context of ovarian structures. It does not refer to any stage of follicle development or luteinization, making this option incorrect.
B) Corpus albicans
The corpus albicans is a fibrous scar tissue that forms when the corpus luteum degenerates after it has completed its function. It does not form from the luteinization of the follicle but rather from the regression of the corpus luteum, thus this option is incorrect.
C) Corpus luteum
The corpus luteum is the correct answer as it is formed from the luteinization of the collapsed follicle after ovulation. This structure is essential for secreting hormones necessary for preparing the uterus for potential pregnancy.
D) Corpus albicans
This option is a repeat of option B and, as previously mentioned, refers to the scar tissue resulting from the regression of the corpus luteum. Therefore, it is not relevant to the question of what structure is formed from luteinization.
Conclusion
The corpus luteum is definitively the correct answer as it directly results from the luteinization process of the collapsed follicle. All other options either do not represent a structure formed during this process or refer to stages that occur after the corpus luteum has performed its function.
