Question

multiple choice question
the internal surfaces of the superior and inferior lips each are attached to the gingivae by a thin mucosa fold in the midline, called the
o areolar
o lingual frenulum
o labial frenulum
o gingiva

Explanation:

• The labial frenulum is a thin fold of mucosa that attaches the internal surfaces of the superior and inferior lips to the gingivae in the midline.
• The areolar is a circular area around the nipple (not related to lip - gingiva attachment).
• The lingual frenulum is under the tongue (attaches tongue to the floor of the mouth, not lips to gingivae).
• The gingiva is the gum tissue itself, not the fold attaching lips to it.

Answer:

labial frenulum
