Vestibule Region of the Nasal Cavity
Respiratory Mucosa (Nasal Mucosa) | Gross & Microscopic Anatomy
Inside the nasal cavity, the surfaces of the turbinate bones (= nasal conchae) and meatuses are lined (see image below) by respiratory mucosa (= nasal mucosa).
An expanded view of the respiratory mucosa shows more detail about its layered composition.
The densely packed cells in the epithelium are embedded in a thin, adhesive sheet called the basement membrane. Deep to the basement membrane is a thicker layer of loose connective tissue called the lamina propria. Many blood vessels and seromucosal glands are also present in the lamina propria.
