sinuses
The hollow spaces above the nasal cavity are known as the paranasal sinuses. These air-filled cavities are located within the bones of the skull and are connected to the nasal passages. They play a role in reducing the weight of the skull, enhancing voice resonance, and providing insulation for the structures of the head. The main sinuses include the frontal, maxillary, ethmoid, and sphenoid sinuses.
The hollow spaces containing a soft substance are typically referred to as cavities or chambers. In biological contexts, these can include structures like the ventricles of the heart or the sinuses in the skull, which often contain soft tissues or fluids. In geological terms, hollow spaces in rocks or minerals may hold softer materials like clay or other sediments. These cavities play important roles in the function and structure of the systems they are part of.
