Write the Histological Features Of Thyroid Gland
Answers
Answer:
Histologically, the thyroid gland is organized as epithelial cells surrounding colloid-containing pools, called follicles. The colloid is rich in thyroglobulin, a protein possessing many tyrosine residues to which iodine molecules attach to form the thyroid hormones.
The thyroid gland is a bilobular endocrine gland that is found in the neck, anterior and inferior to the larynx. Grossly, the gland appears brownish-red and the left and right lobes are connected by an isthmus.
The main purpose of this organ is to produce, store and secrete the iodine-based hormones triiodothyronine (T3) and thyroxine (T4). These hormones have various effects on fat, protein and carbohydrate metabolism, as well as on the development especially central nervous system and general growth.
