Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord .They are the primary target of infection for common cold viruses such as coronaviruses, influenza virus and rhinoviruses.
Simple columnar epithelium consists of a single layer of tall (columnar cells). Simple columnar epithelium is usually involved in active secretion and/or absorption of material across the single cell layer, or (if ciliated) in movement along the surface. By convention, a stratified epithelium is described according to the shape of cells on its free surface. 2  Regardless of whether the surface cells are squamous, cuboidal, or columnar, the underlying cells are usually cuboidal.
