Follikkelens

Follikkelens is a Norwegian word that translates to "the follicle" in English. In a biological context, a follicle refers to a small, sac-like structure. The most commonly discussed type of follicle is the hair follicle, which is found in the skin of mammals. The hair follicle is a tiny organ responsible for growing hair. It is embedded in the dermis and extends to the epidermis. Within the follicle, specialized cells at the base produce keratin, the protein that forms hair. The hair shaft emerges from the follicle and grows outwards.

Beyond hair, the term follicle can also refer to ovarian follicles in females. These structures within the ovary contain an immature egg cell. As an egg matures, the ovarian follicle grows and develops. At ovulation, the mature follicle ruptures, releasing the egg. There are also lymphoid follicles, which are clusters of lymphocytes found in lymphatic tissue. These play a role in the immune system by housing immune cells and facilitating immune responses. The specific meaning of "follikkelens" depends heavily on the context in which it is used, but it consistently refers to a small, contained structure with a specific biological function.
