Embryology of the Thyroid (Easy to Understand)

The development of the thyroid gland explained in a very simple way. If you are completely new to embryology and you want to understand it quickly, this should be the first video you watch:    • Introduction to Embryology - Fertilis...   Post any questions you have about the video below, I read all the comments: -------------------------------- Recommended Text -------------------------------- Easy Embryology is a book that is dedicated to the simplification of embryology.

This location is the foramen cecum. Thyroid begins as a mass of endodermal tissue! The thyroid descends in front of the pharyngeal gut as a bilobed diverticulum. Throughout its travel down to the neck, the thyroid remains connected to the tongue by a narrow canal called the thyroglossal duct - which should disappear. The thyroid travels all the way down to the anterior part of the hyoid bone, and the laryngeal cartilages and reaches its final position in front of the trachea in the 7th week. By this time, the thyroid should have an isthmus, two lobes, and you have a 50% probability that you have an extra lobe called the pyramidal lobe which you got at this time too. Follicular cells produced colloid and you might even see some thyroxine being produced at this time. The parafollicular cells are from the forth pharyngeal pouch (see previous video for full explanation) - namely from the ultimobranchial body. These C cells produce calcitonin.
