The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Following ovulation, the ruptured follicle transforms into a temporary endocrine structure called the corpus luteum (CL), which secretes progesterone.
Historically, classical theriogenology differentiates the corpus luteum based on whether pregnancy is established or if the animal undergoes a sterile cycle.
Step 2: Detailed Explanation:
Let us define the terminology used for the corpus luteum:
- Corpus luteum verum (often spelled 'vernum' in textbooks): This is the "true" corpus luteum, also known as the corpus luteum of pregnancy.
It remains functional throughout gestation (or a significant portion of it) to maintain pregnancy by continuously secreting progesterone.
- Corpus luteum spurium: This is the "false" or transient corpus luteum of a regular, non-pregnant estrous cycle.
If pregnancy does not occur, prostaglandin F2-alpha released by the uterus causes luteolysis of this structure, leading to a new cycle.
Step 3: Final Answer:
Thus, the corpus luteum of pregnancy is formally referred to as Corpus luteum vernum (verum).
