@viscera3d: The thyroid gland is a vital organ of the endocrine system, positioned on the anterior surface of the neck in front of the trachea and inferior to the larynx. It synthesizes thyroid hormones (thyroxine T4 and triiodothyronine T3), which regulate basal metabolic rate, tissue growth and development, and systemic energy homeostasis. #endocrinology #anatomy #physiology #thyroid #3danatomy
