What is Graafian follicle and ovarian follicle?

The ovarian follicles, sometimes called graafian follicles, are rounded enclosures for the developing ova in the cortex near the surface of the ovary. At birth and in childhood they are present as numerous primary or undeveloped ovarian follicles.

What is Graafian follicle explain?

The Graafian follicle is the follicular stage after the first meiotic division but before ovulation. It therefore contains a 2N haploid oocyte. When released from the Graafian follicle and into the oviduct, the ovum will contain three layers: oocyte, zona pellucida and corona radiata. …

During which stage of the ovarian cycle does the Graafian follicle develop?

The Graafian follicle is the stage after the first meiotic division has completed but before ovulation. The oocyte is now a 2N haploid. The follicle is characterized by a large follicular antrum that makes up most of the follicle.

How are the follicles developing in the ovary?

A cross-section of an ovary will reveal follicles in various stages of development. The next sections will describe the histological features of each stage of follicular development and the major functional changes in the cells compose follicles.

When does the Graafian follicle begin meiosis II?

A mature (Graafian) follicle is characterized by the development of a liquid-filled cavity called the Antrum. Immediately prior to ovulation, the Graafian follicle begins Meiosis II and arrests at Metaphase II. This process is only completed if the oocyte is fertilized.

What are the characteristics of a mature follicle?

Once the MVP of our oocytes is chosen, it continues to grow in size until it reaches maturity. The tertiary follicle stage is characterized by the presence of a large, fluid-filled space inside the mature follicle, or graafian follicle, which is just another term for a mature follicle.

What are the two main phases of the ovarian cycle?

Understand what the ovarian cycle is and know the two main phases. Define the follicular phase and the luteal phase. List the steps that the follicular phase involves, including the primordial follicle stage, the primary follicle stage, the secondary follicle stage, the tertiary follicle stage and ovulation.
