Options

A. Antrum
B. Centrocoel
C. Blastocoel
D. Archenteron.

Answer

**Step-by-Step Solution:**

1. **Understanding the Graafian Follicle**: The Graafian follicle is a mature ovarian follicle that is involved in the female reproductive system. It plays a crucial role in the process of oogenesis, which is the development of ova (egg cells).

2. **Formation of Oocytes**: During oogenesis, the primary oocyte is formed from the oogonia. This primary oocyte undergoes meiosis but gets arrested in prophase I until ovulation occurs.

3. **Development of Follicles**: As the primary oocyte develops, it is surrounded by layers of granulosa cells, forming what is known as a primary follicle. As these follicles mature, they develop into secondary follicles and eventually into tertiary follicles, which are also referred to as Graafian follicles.

4. **Cavity Formation**: Within the Graafian follicle, a fluid-filled cavity forms as the follicle matures. This cavity is crucial for the development of the oocyte and is known as the antrum.

5. **Identifying the Correct Option**: The question asks for the name of the cavity contained in the Graafian follicle. Among the options provided:
- a. Androm
- b. Centrosial
- c. Blastocyst
- d. Archentron

The correct answer is **a. Antrum**.

**Final Answer**: The cavity contained in the Graafian follicle is called the **antrum**.
