Match the following structures with their correct descriptions: primordial follicle | A mature follicle that releases an egg during ovulation. primary follicle | A single layer of squamous cells surrounds the arrested primary oocyte. graafian follicle | One cell thick layer of cuboidal cells surrounds the primary oocyte. secondary follicle | The oocyte secretes activin, stimulating granulosa cells to proliferate.
Understand the Problem
The question requires matching four types of ovarian follicle structures with their corresponding definitions. It's necessary to understand the characteristics of each follicle type to correctly pair them with the appropriate description.
Answer
Primordial follicle: squamous cell layer | Primary follicle: cuboidal cell layer | Graafian follicle: mature, releases egg | Secondary follicle: secretes activin.
Primordial follicle: A single layer of squamous cells surrounds the arrested primary oocyte. Primary follicle: One cell thick layer of cuboidal cells surrounds the primary oocyte. Graafian follicle: A mature follicle that releases an egg during ovulation. Secondary follicle: The oocyte secretes activin, stimulating granulosa cells to proliferate.
Answer for screen readers
Primordial follicle: A single layer of squamous cells surrounds the arrested primary oocyte. Primary follicle: One cell thick layer of cuboidal cells surrounds the primary oocyte. Graafian follicle: A mature follicle that releases an egg during ovulation. Secondary follicle: The oocyte secretes activin, stimulating granulosa cells to proliferate.
More Information
In folliculogenesis, the primordial follicle is the most primitive type, characterized by a single squamous cell layer. As follicles mature, layers become more complex, and eventually, the Graafian follicle releases an oocyte during ovulation. This cycle is crucial for reproduction.
Tips
A common mistake is confusing the cell type surrounding the oocyte in different follicle stages: distinguishing squamous from cuboidal cells is essential.
