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).

Along the image descriptionluminal (nasal) surface is pseudostratified ciliated columnar epithelium. Interspersed among the columnar cells in the epithelium are many flask-shaped image descriptiongoblet cells.

The densely packed cells in the epithelium are embedded in a thin, adhesive sheet called the image descriptionbasement membrane. Deep to the basement membrane is a thicker layer of loose connective tissue called the image descriptionlamina propria. Many image descriptionblood vessels and image descriptionseromucosal glands  are also present in the lamina propria.
