"The thyroid gland develops from the proximal primitive foregut between the first and second pharyngeal pouches at the foramen caecum, in the midline of the base of the tongue. During the 5th embryonic week, a diverticulum forms at the foramen that migrates inferiorly, anterior to the body of the hyoid bone, curving posteriorly and superiorly to reach behind the bone before once more turning inferiorly and continuing anterior to the larynx, forming the thyroglossal duct 1,3,7. The duct's tip bifurcates, forming the gland's two lobes. The parafollicular cells (C cells) responsible for calcitonin production are derived from separate tissue, the ultimobranchial body, a small diverticulum of the fourth pharyngeal pouch 7."
