The FSH hormone or follicle stimulating hormone
False. The zona pellucida is formed as the primary oocyte within the primordial follicle begins to grow and develop into a secondary follicle.
A hair follicle typically has a cylindrical shape.
After ovulation, the ovarian follicle produces progesterone.
FSH causes the follicle to create estrogen.

The nail itself is dead, but the follicle that produces it is still alive.
No, the nail plate does not originate from a keratin-containing follicle. Instead, it is formed from specialized epithelial cells in the nail matrix, located under the base of the nail. These cells produce keratin, which hardens to form the nail plate as it grows out. The process is similar to hair growth, but nails do not develop from hair follicles.
Yes, unlike a hair above the follicle, or the visible part of a nail. The skin is regarded as an organ.
Follicle development occurs in several stages: primordial follicle, primary follicle, secondary follicle, preantral follicle, antral follicle, and mature (Graafian) follicle. Each stage involves specific changes in the follicle and oocyte as they mature towards ovulation.

Graafian follicle
Follicle.
The FSH hormone or follicle stimulating hormone
The increase in levels of follicle-stimulating hormone (FSH) that occurs at puberty stimulates the maturation of a primary follicle in the ovary. FSH acts on the granulosa cells of the primary follicle, promoting their proliferation and differentiation. This leads to the growth and development of the primary follicle into a secondary follicle.
