Where is the vestibule of the nose located?

The vestibule is the anterior entryway to the nasal cavity, located just inside the external openings of the nose (the nostrils). This area is lined with skin and contains coarse hairs (vibrissae) that help trap large particles before air reaches the deeper nasal mucosa. As you move inward, the mucous-lined cavity proper begins. The boundary between the vestibule and deeper nasal cavity is the limen nasi. The other locations described are not correct because they refer to areas behind the nostrils or outside the nose, not the inside entrance of the nasal cavity.
