Histology of Thyroid

Thyroid gland consists of colloid follicles which are lined by cuboid epithelial cells secreting the thyroid hormones, triiodothyronine (T3) and thyroxine (T4). Between the follicles is the interstitial space, containing the blood vessels and the parafolliclar (C) cells responsible for the secretion  of calcitonin.
