Oral Mucosa Quiz: Functions, Development, and Histological Structure

The oral mucosa protects the deeper tissues from mechanical forces resulting from mastication and from the abrasive nature of foodstuffs.

Receptors in the oral mucosa respond to temperature, touch, pain, and taste.

The major secretion associated with the oral mucosa is saliva, which is produced by the salivary glands to maintain the moist surface of the mucosa and to assist in mastication, swallowing of food, and speech.
