The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Term "Antrum":** - The term "antrum" refers to a cavity within a biological structure. In the context of the reproductive system, it is most commonly associated with the ovarian follicles. 2. **Identifying the Type of Antrum:** - The antrum in the ovaries is specifically known as the "follicular antrum." This cavity is significant during the development of ovarian follicles. 3. **Characteristics of the Follicular Antrum:** - The follicular antrum is a fluid-filled cavity that develops as the primary follicle matures into a secondary follicle. The presence of this antrum indicates that the follicle is progressing in its development. 4. **Role in Ovarian Follicle Development:** - As the primary follicle matures into a secondary follicle, the antrum forms and fills with fluid. This is a crucial step in the maturation process, leading eventually to the formation of a tertiary follicle, also known as the Graafian follicle. 5. **Conclusion:** - Based on the information, the correct definition of the antrum is that it is a fluid-filled cavity within the follicle, specifically referring to the follicular antrum in the ovaries. ### Final Answer: - The antrum is the fluid-filled follicle cavity.
