Thyroid model


The model displays the larynx and thyroid gland. The thyroid gland is an endocrine organ. Located below the thyroid cartilage in the neck, on both sides of the trachea. The human thyroid gland is named after a reddish brown gland, resembling a shield armor.
The thyroid gland is the largest endocrine gland in adults, located in the anterior part of the neck. It is reddish brown and H-shaped, with an average weight of 26.71g for males and 25.34g for females; Composed of left and right lobes, isthmus, and conical lobes. The left and right lobes of the thyroid gland are conical in shape (the right lobe is slightly larger), attached to the side of the larynx and trachea. The upper end reaches the middle of the thyroid cartilage, and the lower end reaches the 4th tracheal ring. They are about 5cm long and 2.4cm wide, and the inner side is attached to the cricoid cartilage through the lateral ligament. Therefore, during swallowing, the thyroid gland can move up and down with the larynx. The thyroid isthmus connects the left and right lobes, located in front of the 2-4th tracheal cartilage ring. In a few cases, the thyroid isthmus may be absent. About 50% of people have a conical lobe protruding upwards from the isthmus of the thyroid gland. Conical leaves vary in length, some reaching the level of the hyoid bone
