Foliküles

Foliküles is a term used in biology to describe a small sac or cavity, particularly within an organ. The most common usage of the term refers to hair follicles, which are small structures in the skin from which hair grows. Each hair follicle contains a root that anchors the hair and a bulb that produces new hair cells. These follicles are essential for hair regeneration and play a role in various skin functions.

Beyond hair, the term foliküles can also refer to ovarian follicles. These are small, fluid-filled sacs within the ovary that contain an immature egg cell. During the menstrual cycle, one or more ovarian follicles develop and mature, eventually releasing an egg for potential fertilization. This process, known as ovulation, is a critical component of female reproduction.

In other contexts, foliküles might be used to describe structures within glandular tissues, where they can hold secretions. The specific function and nature of a folikül are determined by the organ or tissue in which it is found. Understanding the structure and function of these various types of foliküles is important in fields ranging from dermatology and reproductive medicine to histology.
