arytenoid swelling visceral pleura parietal pleura tracheoesophageal septum superior laryngeal nerve endoderm laryngotracheal groove splanchnic mesoderm right bronchus recurrent laryngeal nerve left bronchus trachea bronchopulmonary segments
1. The primordial of the lower respiratory system
2. It gives rise to the epithelium and glands of the larynx, trachea, bronchi, and
pulmonary epithelium
3. It gives rise to the connective tissue, cartilage and smooth muscle
4. It divides the foregut into dorsal and ventral part
5. Nerve supply to larynx that develop from the 4th pharyngeal arches
6. Nerve supply to larynx that develop from the 6th pharyngeal arches
7. It is formed at the cranial end of the laryngotracheal tube by the proliferation of
the mesenchymal tissue.
8. It covers the lung and is forms by the mesodermal layer
9. It develops from repeatedly dividing secondary bronchi
10. The size is larger and more vertical
