The structure formed after release of ova from graafian follicles and secretory in nature is

Options

A. Corpus callosum
B. Corpus luteum
C. Corpus albicans
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question asks about the structure that forms after the release of an ovum (egg) from the Graafian follicle during ovulation.

2. **Identifying the Process**: When the ovum is released, the Graafian follicle ruptures. This process is known as ovulation.

3. **Formation of the Corpus Luteum**: After ovulation, the remnants of the Graafian follicle transform into a new structure called the corpus luteum.

4. **Function of the Corpus Luteum**: The corpus luteum is a secretory structure, meaning it produces hormones. It primarily secretes progesterone and estrogen, which are crucial for maintaining the menstrual cycle and supporting early pregnancy if fertilization occurs.

5. **Characteristics of the Corpus Luteum**: The corpus luteum has a yellowish color due to the presence of a pigment called lutein, which is produced during its formation.

6. **Outcome of Fertilization**: If the ovum is fertilized, the corpus luteum continues to function and produce hormones to support the pregnancy. If fertilization does not occur, the corpus luteum degenerates into a fibrous structure known as the corpus albicans.

7. **Conclusion**: Based on the above information, the correct answer to the question is that the structure formed after the release of the ovum from the Graafian follicle is the **corpus luteum**.

**Final Answer**: The structure formed after the release of ova from Graafian follicles and secretory in nature is **corpus luteum**.
