Simple epithelium : pseudostratified ciliated columnar epithelium

 The respiratory tract and a few other specific places are home to pseudostratified ciliated columnar epithelium, a specialized form of epithelium. A detailed paragraph outlining its main attributes and capabilities can be found below:
The single layer of cells that makes up pseudostratified ciliated columnar epithelium seems stratified because of the different locations of their nuclei, but it is not actually multilayered. Not all of the cells reach the apical surface, but they all rest on the basement membrane. The cilia on the apical surface of this epithelium are what distinguish it and are essential for the passage of mucus and trapped particles. Goblet cells, which are scattered among the columnar cells, help with protection and filtration by secreting mucus to capture dust, debris, and microbes.

This tissue is frequently seen lining the respiratory tract, which includes the trachea, bronchi, and nasal cavity. It helps remove pollutants from the airways by participating in the mucociliary escalator mechanism. The pseudostratified structure preserves the protective barrier while enabling effective surface area utilization for secretion and mobility. This epithelium is critical for respiratory health and for preserving airway hygiene.
