Goblet cell
Goblet Cell
Goblet cells (/ˈɡɒblɪt sɛl/; from Latin goblet, "cup") are simple columnar epithelial cells that secrete mucin, which forms mucus. They are scattered among the epithelial lining of organs, such as the intestinal and respiratory tracts.
Etymology
The term "goblet" refers to the cell's goblet-like shape. The name was coined by Swiss anatomist Auguste Forel in the 19th century.
Function
Goblet cells play a crucial role in maintaining the health of the mucous membranes. They produce and secrete mucus, a thick protective fluid. The mucus traps unwanted materials like dust and bacteria, preventing them from reaching the internal tissues.
Structure
Goblet cells are simple columnar epithelial cells, meaning they have a height much greater than their width. The apical portion is shaped like a cup, which gives the cell its goblet-like appearance. The nucleus is located at the base of the cell.
