The paranasal sinuses, air-filled cavities within the skull, play a vital role in respiratory health and cranial structure, named after the bones they occupy. This image illustrates their locations, including the frontal sinus above the eyebrows, the maxillary sinuses below the orbits, the sphenoid sinus under the sella turcica, and the ethmoid air cells between the orbit and nasal cavity. This article explores the anatomical positioning, physical characteristics, and functional significance of these sinuses, offering a detailed guide for understanding their role in human anatomy.
