follikkelikanavan

Follikkelikanalan is a term used in anatomy to denote a channel or duct that is associated with a follicle. Its exact meaning can vary depending on the organ system being described, and the term is more common in older or regional anatomical texts than in modern, standardized terminology.

In the context of the skin and hair, the follicle canal refers to the passage through which the hair shaft grows from the hair bulb to the skin surface. This canal is lined by epidermal cells and forms part of the pilosebaceous unit. The upper portion of the canal often communicates with the sebaceous gland duct. Proper function of the follicle canal is important for normal hair growth and skin health; obstruction or inflammation of this canal can contribute to conditions such as folliculitis or acne.

In ovarian or reproductive anatomy, the term is not standard in contemporary textbooks. When encountered, it may be used loosely to describe a conduit related to follicular structures, but precise terminology typically centers on the follicle itself, the antrum, and surrounding stromal tissues rather than a universal “follicle canal.”

In other organs, the phrase may appear in historical or descriptive usage to indicate a duct or channel connected to a follicle, but it is not a universally defined structure in modern anatomy.

Etymology derives from the Latin roots for small bag (folliculus) and canal, reflecting its role as a channel associated with a follicular unit. See also: hair follicle, ovarian follicle, sebaceous gland.
