Contact with mucous membranes, such as eyes or mouth describes which term?

• A. Permicosal
• B. Perimucosal
• C. Periorbital
• D. Permeable

Answer: (A)

The main idea is describing exposure that involves the mucous membranes. The term that fits is perimucosal, built from peri- meaning around and mucosal referring to mucous membranes (the eyes, mouth, nose, etc.). When contact targets these surfaces, we say it’s perimucosal exposure. This differs from terms that pinpoint a specific area (like around the eye) or describe a material’s property (such as permeable, which means easily allowing substances to pass through). In many tests you’ll see a spelling variant of this term, but the meaning is the same: contact with mucous membranes.
