 name: stratum corneum of esophageal epithelium
-def: "The outermost layer of the stratified squamous epithelium lining the esophagus, composed of several layers of flattened, anucleated keratinocytes called corneocytes. It forms the primary protective barrier against mechanical, chemical, and microbial insults, while regulating permeability and contributing to tissue integrity. This layer is characterized by corneocytes embedded in a lipid-rich extracellular matrix, providing mechanical reinforcement and maintaining essential barrier functions of the esophageal lining." []
