Unicellular gland
An electron micrograph shows the expanded upper portion of a goblet cell intercalated in the ciliated epithelium of the trachea. The contents of the poorly defined mucin granules are expelled onto the surface of the epithelium, forming a sheet of mucus that traps inhaled particles. 8000x
