The delicate lining of the mouth and the oesophagus is primarily composed of squamous epithelium.

Epithelial tissue forms the lining of body cavities, surfaces, and organs. The inner lining (mucosa) of the mouth and oesophagus, which is subject to abrasion from food passage, is lined with stratified squamous epithelium. This type of epithelium is composed of multiple layers of flattened cells, providing a protective barrier. Injury to this lining directly affects this epithelial tissue.

Smooth muscle is found in the muscular layers of the oesophagus wall, responsible for peristalsis (moving food down), but not the lining itself. Cuboidal epithelium is typically found in glands and kidney tubules. Striated muscle (skeletal muscle) is involved in voluntary movements, such as swallowing initiation, but does not form the lining.
