Thyroid Body
or GLAND, in anatomy, a soft, reddish and highly-vascular organ, consisting of two lateral lobes united by their lower ends by a transverse portion called the isthmus. It forms a rounded projection upon the trachea and larynx. It is one of the vascular glands, or glands without ducts. It has an important relation with the functions of the brain. The removal of the gland causes loss of mental vigor. Goiter is a disease of this gland, and in extreme cases, extirpation is resorted to.
