ANATOMY

Detailed explanation-1: -The space inside the nose. The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. It is divided into two sections called nasal passages. Air moves through these passages during breathing.

Detailed explanation-2: -Nerve cells: These cells communicate with your brain to provide a sense of smell. Nostrils (nares): These are the openings to the nasal cavities that are on the face. Septum: The septum is made of bone and firm cartilage. It runs down the center of your nose and separates the two nasal cavities.

Detailed explanation-3: -Supportive Bones and Cartilages of the Nasal Cavity The nasal cavity is posterior to the nose and is framed and supported by several bones and cartilages. The nasal septum divides the nasal cavity into two chambers.

Detailed explanation-4: -Your cheekbones hold your maxillary sinuses (the largest). The low-center of your forehead is where your frontal sinuses are located. Between your eyes are your ethmoid sinuses. In bones behind your nose are your sphenoid sinuses.

Detailed explanation-5: -There are four paranasal sinuses, each corresponding with the respective bone from which it takes its name: maxillary, ethmoid, sphenoid, and frontal.
