After ovulation the structure formed by the rupture of follicle is known as:

Options

A. Corpus albicans
B. Corpus luteum
C. Corpus callosum
D. Corpus mammilare

Answer

**Step-by-Step Solution:**

1. **Understanding Ovulation**: Ovulation is the process where an ovum (egg) is released from the ovarian follicle. This typically occurs around the 14th day of the menstrual cycle.

2. **Follicle Rupture**: During ovulation, the mature follicle, known as the Graafian follicle, ruptures to release the ovum.

3. **Formation of Corpus Luteum**: After the ovum is released, the remaining part of the Graafian follicle transforms into a structure called the corpus luteum.

4. **Function of Corpus Luteum**: The corpus luteum plays a crucial role in the menstrual cycle by secreting hormones, primarily progesterone, which helps prepare the uterus for a potential pregnancy.

5. **Degeneration of Corpus Luteum**: If fertilization does not occur, the corpus luteum eventually degenerates and transforms into a structure known as corpus albicans.

6. **Final Answer**: Therefore, the structure formed by the rupture of the follicle after ovulation is known as the **Corpus Luteum**.
