Place the following terms in order of the ovarian cycle. Play Ovulation Primordial follicle Play Corpus albicans Play Corpus luteum Play Play Secondary follicle Primary follicle Mature follicle Reset
The Correct Answer and Explanation is :
The correct order of terms in the ovarian cycle is as follows:
- Primordial follicle: This is the earliest stage of the ovarian follicle, where the oocyte (egg cell) is surrounded by a single layer of flattened granulosa cells.
- Primary follicle: The primordial follicle develops into the primary follicle, where the granulosa cells become cuboidal, and the oocyte enlarges.
- Secondary follicle: The primary follicle develops into a secondary follicle, where fluid-filled spaces begin to form between the granulosa cells, and the theca layer (the outer layer of the follicle) forms.
- Mature follicle (also called a Graafian follicle): The secondary follicle matures into a large, fluid-filled mature follicle, also known as a Graafian follicle. This is the stage just before ovulation.
- Ovulation: During ovulation, the mature follicle ruptures and releases the oocyte (egg) into the fallopian tube.
- Corpus luteum: After ovulation, the empty follicle transforms into the corpus luteum, which secretes progesterone to support pregnancy if fertilization occurs.
- Corpus albicans: If pregnancy does not occur, the corpus luteum degenerates and becomes the corpus albicans, a scar-like tissue.
This sequence describes the stages of follicular development and the hormonal changes involved in the ovarian cycle. Each step prepares the follicle and the body for ovulation, and the presence or absence of pregnancy dictates the fate of the corpus luteum.
