Which type of cells are primarily found in the mucous membrane lining the sinuses?

The mucous membrane lining the sinuses is primarily composed of ciliated epithelial cells. These specialized cells play a crucial role in maintaining the health and functionality of the respiratory system. The cilia are tiny, hair-like projections that extend from the surface of the epithelial cells and help to move mucus, along with trapped particles and pathogens, out of the sinuses and towards the throat. This action is vital for keeping the sinuses clear and free from infection and irritation.

Ciliated epithelial cells are specifically adapted to their environment, allowing for effective mucociliary clearance, which is essential in preventing sinusitis and other respiratory issues. The presence of these cells highlights the importance of this lining in protecting the body against airborne pathogens and facilitating proper airflow in the sinus cavities. The other types of cells listed, such as skeletal muscle cells, connective tissue cells, and adipose cells, do not play a direct role in the function of the sinus mucous membrane.
