What are the two membranes found in the cornea?

• A. Sclera and choroid
• B. Bowman's and Descemet
• C. Ganglion and inner nuclear
• D. Epithelial and Endothelial

Answer: (B)

Understanding corneal structure includes recognizing two membranes that lie between its main layers: Bowman's layer and Descemet's membrane. Bowman's layer sits just beneath the corneal epithelium; it’s a tough, acellular layer that provides a bit of rigidity. Descemet's membrane lies between the stroma and the endothelium and acts as the basement membrane for the endothelial layer. These two membranes are characteristic features of the cornea itself, differentiating them from other ocular structures like the sclera or choroid, retinal layers such as the ganglion or inner nuclear layer, or the simple cellular layers of epithelium and endothelium.
