1. Vestibule: The area lying just posterior to the nostrils, this is the part of the nasal cavity
most exposed to the environment
2. Respiratory region: It begins at the end of the vestibular area, and includes the entire

This region has a ciliated pseudostratified epithelium lining (single cell layer) containing goble
cells ,that secrete mucus that forms the mucus membrane.
