Respiratory system
Nostrils, or nares (nar-eeze) for plural, naris for singular, and nasal ala (wings)
Root (or glabella, between eyebrows), nasal bridge, dorsum nasi, nasal apex, philtrum
The skin covering the nasal bridge is thin with many sebaceous glands, whereas the edges of the nose (ala) has dense fibrous tissue, the major alar cartilages.
Nasal cavity
Nasal septum, anterior
Vomer bone and ethmoid bone perpendicular plat, posterior
Posterior nasal apertures, also known as choanae (funnels), are separated by the vomer bone
Ethmoid and sphenoid bones of skull, roof of nasal cavity
Palate, nasal cavity floor
The palatine bones and processes of the maxillary bones are supported by the hard palate, which is anterior
Unsupported by the muscular soft palate
Nasal vestibule, hair and sweat glands
The remaining nasal cavity has 2 types of mucous membranes, olfactory mucosa and respiratory mucosa
Pseudostratified ciliated columnar epithelium with scattered goblet cells in lamina propria
Mucous cells make mucous, serous cells make clear fluid filled with enzymes (serous fluid)
Superior, middle, inferior nasal conchae and their nasal meatus have a scroll-like shape, which mechanically prevents particles > 6µm
