Stratified epithelia contain two or more layers of cells. The function of this type of epithelium is mostly protective – the higher the number of layers, the more protective it is. … This type of epithelium can either be keratinising (i.e. the skin) or non-keratinising (i.e. the oesophagus).

They are cube shaped cells found in kidney tubules,ducts of salivary glands. They act as gland cell ie secrete substances at the epithelial surface. Sometimes a portion of tissue folds inwards and a multicellular gland is formed. This is called glandular epithelium. What is glandular epithelial tissue? Glandular epithelium isRead More →

Analogous to neural glial cells, the supporting cells are non-neural cells in the olfactory epithelium that are located in the apical layer of the pseudostratified ciliated columnar epithelium. There are two types of supporting cells in the olfactory epithelium: sustentacular cells and microvillar cells. Is olfactory mucosa ciliated? The ciliatedRead More →
