Pseudostratified columnar epithelium
The lining epithelium of the monkey trachea demonstrates a pseudostratified epithelium with cilia and gland cells, called goblet cells. Goblet cells release mucin proteins which, when hydrated, form mucus. The mucus traps inhaled particles and the entire mucous sheet is moved upwards by the beating action of the cilia. 1200x
