Quizplus · Accepted Answer

The free gingiva, a component of the gingival unit, extends from the gingival margin to the base of the gingival sulcus. It is the attached gingiva that extends from the base of the sulcus to the mucogingival junction; the question incorrectly identified this as the alveolar mucosa. The mucogingival junction divides the very dense masticatory mucosa of both the free and attached gingiva from the alveolar mucosa. While cells of the gingiva, both free and attached, have a thick epithelial covering and keratinized cells, the rest of the mouth is lined with thin and nonkeratinized lining mucosa.
