Thyroid follicle containing colloid

WebbWhen the follicular cells are stimulated to produce thyroid hormones, droplets of the colloid are taken up by endocytosis into the cell, to form vesicles. These vesicles fuse with lysosomes, which contain enzymes that cut the thyroglobulin to release the pairs of iodinated tyrosine residues. WebbThe thyroid is brownish-red in color, is a highly vascular gland and is composed of multiple lobules separated by thin septations. Each lobule consists of 20-40 follicles and supplied by an intralobular artery. The thyroid is characterized by three main histological features: colloid containing follicles, follicular epithelium, and ...
