Oral Mucosa Quiz (ODS Learning Outcomes)

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.

Description

Explore the distinct types of oral mucosa including lining, masticatory, and specialized mucosa. This quiz delves into their histological characteristics and the specific areas of the oral cavity where they are found. Test your knowledge on the structure and function of oral tissues.
