Thyroid Gland Development cartoon
- The thyroid gland begins to develop as a median thickening of endoderm on the floor of the pharynx between the first and second pharyngeal pouches.
- This area later invaginates to form the median diverticulum, which appears in the later half of the fourth week.
- This thyroid diverticulum grows further, becoming a solid cellular cord called the thyroglossal duct.
- The duct grows caudally and bifurcates to give rise to the thyroid lobes and the isthmus.
