The distinguishing characteristic of a tertiary follicle is a fluid-filled cavity called ________ Correct Answer Antrum
Primary follicle is formed by the primary oocyte arrested at Prophase I and enveloped by a layer of granulosa cells. These are then enveloped by a theca resulting in a secondary follicle, which further undergoes development resulting in the formation of a fluid-filled cavity called the antrum. This mature follicle is a tertiary follicle.
