Study Notes
Soft Palate
- The soft palate's epithelium is non-keratinized and continuous with the hard palate's epithelium
- A line, known as the "healthy" or "Ah" line, separates the hard and soft palate
- The lamina propria is separated from the submucosa by a continuous layer of elastic fibers, allowing for mobility
Mucous Membrane
- Non-keratinized mucosa is found in the soft palate, tongue, buccal mucosa, floor of the mouth, and inferior surface of the tongue
- The submucosa contains fat cells and mucous glands
Lip
- The lip consists of a mucous membrane side and a skin side
- The mucous membrane side has a vermilion zone and a non-keratinized stratified squamous epithelium
- The skin side has sebaceous glands and hair follicles
- Mixed glands are present in the lip, including salivary glands
- A vermilion border separates the mucous membrane side from the skin side
This quiz covers the anatomy of the oral palate, including the epithelium, hard and soft palate, and surrounding tissue structures.
