Question 3

List two functions of the paranasal sinuses.

Accepted Answer

The paranasal sinuses are air-filled spaces located within the bones of the skull and face. They are connected to the nasal cavity and lined with mucous membranes. The paranasal sinuses include the frontal, ethmoid, sphenoid, and maxillary sinuses. They serve several important functions:

1. Humidification and Warming of Inhaled Air: The paranasal sinuses contribute to the conditioning of the air we breathe in. As air passes through the nasal cavity and sinuses, it is humidified and brought to body temperature before reaching the lungs. This helps to protect the respiratory tract and enhance the efficiency of gas exchange in the lungs.

2. Resonance of Voice: The sinuses act as resonating chambers for the voice. They help to amplify and give quality to our voice by adding depth and tone. This is why our voice can sound different when we have a sinus infection or congestion, as the normal resonance is disrupted.

In addition to these functions, the paranasal sinuses also play roles in reducing the weight of the skull, providing insulation for the brain, and serving as a crumple zone to protect vital structures during facial trauma. They also contribute to the immune defense by trapping and clearing pathogens and particulate matter from the air we breathe.
