Thyroid Anatomy diagram. The thyroid is a gland located in the neck that generates hormones to control many body functions. Because the thyroid gland is a hormone secreting organ, it is highly vascularized. It receives blood from the superior and inferior thyroid arteries. It is a butterfly shaped organ made of two lobes, one on the right and the left as the wings, and the narrow connecting isthmus as the body. The thyroid arises from a downward outpouching of the floor of the pharynx. Thyroid anatomy chart below.
