Follicular

Follicular (lat. follicularis) - related to follicles.

Follicles are small glandular structures consisting of groups of cells lining a small cavity or lumen. Follicles are found in many organs and tissues of the body, for example:

1. Hair follicles are pouch-shaped depressions in the epidermis in which hair is formed.

2. Thyroid follicles are structural units of the thyroid gland that produce the hormones thyroxine and triiodothyronine.

3. Ovarian follicles - in the early stages of egg development, later - the corpus luteum.

Thus, the term "follicular" is used to describe structures associated with follicles - follicular cells, follicular fluid, follicular adenoma (benign tumor), etc. This term is widely used in histology, endocrinology and other medical disciplines.
