Oesophagus epithelium. Coloured scanning electron micrograph (SEM) of the epithelium (lining) of the oesophagus. The irregularly-shaped epithelial cells (blue & yellow) have a highly folded surface. These tiny folds are called microplicae. The flattened cells form a stratified squamous epithelium many layers thick. As a muscular non- absorptive tube,the oesophagus transports swallowed food to the stomach. The microplicae keep the oesophagus moist,trap mucus to lubricate passing food and protect the epithelium from food abrasion. Magnification unknown | |
