Its cells develop from the follicular cells surrounding the ovarian follicle. Eggs are deposited in the sebaceous gland inside the hair follicle. The thecal cells around each follicle secrete estrogen. Normally, sebaceous glands are only found in association with a hair follicle. Comedones are associated with the pilosebaceous unit, which includes a hair follicle and sebaceous gland. Removal of the oocyte from the follicle causes meiosis to progress in the oocyte. The follicle and the ovary's wall rupture, allowing the secondary oocyte to escape. They also consist of granulosa cells and theca of follicle. Hair growth begins inside the hair follicle. The muscle cells connected to the hair follicle have been visualized by actin immunofluorescence. Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Both must reach a threshold for the proliferation of hair follicle cells. The telogen phase is the resting phase of the hair follicle. The primary role of the follicle is oocyte support. Ovulation occurs about 109 hours after the start of follicle growth.
