What do the turbinal bones contribute to in the skull?

The turbinal bones, also known as nasal conchae, play a critical role in the structure of the nasal cavity. They are located on the lateral walls of the nasal cavity and assist in conditioning the air we breathe by increasing the surface area within the nasal cavity. This anatomical feature helps to warm, humidify, and filter the air as it passes through, which is essential for respiratory health.

In contrast to the turbinal bones, the support for the jaw is primarily provided by the mandible and the relevant muscles, while the protection of the eyes is primarily managed by the orbital bones surrounding the eye sockets. The formation of the cheekbones is associated with the zygomatic bones, rather than the turbinal bones. Therefore, the turbinal bones' main contribution to the skull is indeed their significant role in forming and structuring the nasal cavity.
