Holmes' Silver Nitrate Method demonstrates which neural structures?

• A. Axons, nerve fibers, and neurofibrils
• B. Glial fibers
• C. Neuronal cell bodies
• D. Blood vessels

Answer: (A)

Holmes' Silver Nitrate Method is a silver staining technique that highlights the neural extensions and the cytoskeletal framework inside neurons. It deposits silver on the neurofilaments that run along axons and through dendrites, making the axons and nerve fiber networks stand out. This focus on the fine processes and their supporting filaments means the method emphasizes axons, nerve fibers, and neurofibrils rather than cell bodies, glial elements, or blood vessels. So, the structures most clearly demonstrated are the axons, nerve fibers, and neurofibrils.
