Which corneal membrane lies between the posterior stroma and the endothelial cells and can be repaired by the endothelium?

Descemet's membrane is the basement membrane secreted by the corneal endothelium, forming the boundary between the posterior stroma and the endothelial layer. Because it is produced by the endothelium, this membrane can be repaired or rebuilt by endothelial activity when needed. The other structures are located differently: the endothelium itself is the innermost cell layer, the stroma is the thick layer just anterior to Descemet's membrane, and the epithelium is the outermost layer. Remembering that Descemet's membrane sits right after the stroma and is produced by the endothelium helps you see why it’s the correct answer.
