foliküle

Foliküle is a term that generally refers to a small sac or cavity. In biology, the most common usage relates to hair follicles, which are small structures in the skin from which hair grows. Each hair follicle is a complex organ that produces hair. The follicle is a pocket in the epidermis that extends down into the dermis. The root of the hair is embedded within the follicle, and the hair shaft emerges from the skin's surface.

Another biological context for foliküle is in the ovary. Ovarian follicles are fluid-filled sacs within the ovary that contain an immature egg cell. During the menstrual cycle, one or more ovarian follicles develop and mature. When a follicle is mature, it releases the egg cell in a process called ovulation. After ovulation, the ruptured follicle transforms into the corpus luteum, which produces hormones.

Beyond biology, the term foliküle can also be used more generally to describe any small, pouch-like structure. For example, in botany, it might refer to certain reproductive structures. The specific meaning of foliküle is therefore dependent on the context in which it is used. Its core concept, however, remains that of a small, enclosed sac or cavity.
