Detailed explanation-1: -The esophageal lining is protected by a stratified squamous epithelium. Because this epithelium is normally not exposed to dryness or to abrasion, it is non-keratinized. Scattered submucosal mucous glands provide lubrication.
Detailed explanation-2: -Stratified squamous epithelium: This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or protection against water loss. The outer layer of your skin (the epidermis) is made of stratified squamous epithelial cells.
Detailed explanation-3: -The inner lining of the esophagus is known as the mucosa. It is called squamous mucosa when the top layer is made up of squamous cells. Squamous cells are flat cells that look similar to fish scales when viewed under the microscope. Most of the esophagus is lined by squamous mucosa.
