Schneiderian membrane

Human Anatomy

The Schneiderian membrane is the membranous lining of the maxillary sinus cavity. Microscopically, it is a bilaminar membrane. Its internal, or cavernous, side has pseudostratified ciliated columnar epithelial cells, while its osseous side has periosteum. The membrane is also present in the nasal chamber, which helps with smell through olfactory receptors.
