The larynx, or voice box, contains a variety of cell types. The lining of the larynx is primarily composed of respiratory epithelium. This epithelium is characterized by ciliated, pseudostratified columnar epithelium with a significant number of goblet cells. Beneath this epithelial layer lies a submucosa containing a mix of mucous and serous glands.
Beyond the respiratory epithelium, other cell types are present and play crucial roles in the larynx's function and immune response. These include:
- Macrophages: These immune cells engulf and eliminate foreign substances.
- Dendritic cells (DCs): These antigen-presenting cells play a vital role in initiating immune responses.
- T and B lymphocytes: These are key players in the adaptive immune system, contributing to targeted immune defense.
The true vocal cords are an exception, differing slightly in their cellular composition from the rest of the larynx's lining.
The references confirm the presence of the key cell types mentioned above: the respiratory epithelium with its ciliated cells and goblet cells is extensively described. The presence of immune cells like macrophages, dendritic cells, and lymphocytes in the laryngeal mucosa is also supported by the provided research on laryngeal mucosal immunology (https://pmc.ncbi.nlm.nih.gov/articles/PMC2666820/). The role of microbiota in shaping host immunity within the larynx further highlights the complex cellular interactions within this organ (https://www.cell.com/iscience/abstract/S2589-0042(24)01381-6).
