Larynx


Lung development video -Interactive video text

Larynx develops from the 4th and 5th arches. It develops from the caudal hypobranchial eminence which later becomes the epiglottis and the cuneiform cartilages. Laryngotracheal groove is formed at the level of the 6th arch and its opening is further developed to become T shaped. On the sides of the T will be the connection of the two arytenoids swellings.

The arytenoids swelling later forms the arytenoids cartilages. The transverse groove forming the transverse bar of the T will form the ary-epiglottic folds and muscles together with the corniculate cartilages of the larynx. The larngotracheal groove itself forms the respiratory tract. Its proximal end forms the trachea, the middle forms the bronchi while the distal forms the lungs.
