The transition of the lips where the outer skinner and inner mucous membrane meet is called the _________

I looked it up and from what I read I believe it is the gingivae. Would that be correct.

Thank you

No, the transition of the lips where the outer skin and inner mucous membrane meet is not called the gingivae. The gingivae refers to the gums around the teeth.

The correct term for the transition of the lips is the vermillion border. The vermillion border is the sharp demarcation between the red-colored portion of the lips (vermillion) and the normal skin surrounding it. It is more pronounced in some individuals and less distinct in others.

To verify this information, you can search for reliable sources such as medical or dental websites, anatomy textbooks, or professional literature that discuss the anatomy and structure of the lips. Remember to look for credible sources to ensure accurate and trustworthy information.
