Thyroid cartilage
The largest of the cartilages of the larynx (the voice box).
The thyroid cartilage is formed of two approximately quadrilateral plates (called laminae) that are joined anteriorly (in the front) at an angle of from 90° to 120° to create a prominence in the neck.
This bump is called the laryngeal prominence (or, familiarly, Adam’s apple). The thyroid cartilage has nothing to do with the thyroid gland, except for proximity.

two wings (lobes) attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH), which is produced by the pituitary gland, […]
- Thyroid hormone
A chemical substance made by the thyroid gland for export into the bloodstream. The thyroid gland needs iodine to make thyroid hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). The thyroid gland is located in front of the neck just in front of the trachea.

- Thyroid peroxidase test
A blood test done to detect autoantibodies directed against thyroid peroxidase (TPO), an enzyme in the thyroid gland that is very important to the production of thyroid hormones. TPO is found in thyroid follicle cells where it catalyzes the iodination of T4 and T3 in the biosynthesis of thyroid hormones. Autoantibodies to thyroid peroxidase (abbreviated […]
