The thyroid gland is situated beneath the Adam's apple in the front or front region of the neck.
The anatomy of the thyroid gland consists of a butterfly-shaped organ with two lobes joined by a thin isthmus.
The morphology or structure of the thyroid gland includes a functional unit known as the thyroid follicle, which is occasionally bordered by follicular cells and parafollicular cells that enclose a lumen that carries colloid.
Triiodothyronine (T3) hormone and thyroxine hormone are the two main hormones secreted by the thyroid gland (T4).
