Flashcards
Lining Mucosa
Lining Mucosa
A type of mucosa found in areas that require flexibility, such as the inner cheek and lips. It lacks a tough outer layer of keratin, allowing it to stretch.
Masticatory Mucosa
Masticatory Mucosa
A type of mucosa found in areas that need to withstand pressure, such as the gums and hard palate. It has a thicker layer of keratin for protection.
Specialized Mucosa
Specialized Mucosa
A type of mucosa specifically designed for taste and sensation. Found on the tongue, it has specialized structures called papillae.

Study Notes
Types of Oral Mucosa and Their Histopathology
-
Lining mucosa: Non-keratinized stratified squamous epithelium. Found in the buccal mucosa, labial mucosa, alveolar mucosa, floor of the mouth, ventral surface of the tongue, and soft palate.
-
Masticatory mucosa: Para-keratinized stratified squamous epithelium. Located on the attached gingivae, hard palate, and dorsum of the tongue.
-
Specialized mucosa: Para-keratinized stratified squamous epithelium. Characterized by the presence of lingual papillae.
Areas of Oral Cavity Associated with Each Mucosa Type
-
Lining mucosa: Lines the inside of the cheeks (buccal mucosa), lips (labial mucosa), the gums adjacent to the teeth (alveolar mucosa), the floor of the mouth, the underside of the tongue (ventral surface), and the soft palate.
-
Masticatory mucosa: Found on the attached gingiva (the gum tissue firmly attached to the bone), hard palate, and the top surface of the tongue (dorsum).
-
Specialized mucosa: Found on the tongue's surface, specifically covering the lingual papillae.
Changes in Oral Mucosa Appearance
-
Drug-induced changes: Medications can alter the appearance of oral mucosa, leading to various effects.
-
Infectious changes: Infections can manifest as inflamed, ulcerated, or discoloured oral mucosa.
-
Iatrogenic changes: Procedures or treatments (iatrogenic) can sometimes cause adverse effects like ulcers, or inflammation on the oral mucosa.
-
Self-inflicted changes: Oral habits or self-injury can result in wounds, abrasions, or sores on the oral mucosa.
