Yes, we can see some nerves with the naked eye. Larger nerves, like the spinal cord and major nerves going to limbs and organs, are visible as thick white threads.
However, individual nerve fibers are too small to be seen without a microscope. Nerves are made up of many fibers bundled together, and the size of the bundle determines whether it's visible to the naked eye.
- Example: The spinal cord, a large bundle of nerves, can be seen during surgery or dissection.
- Example: The optic nerve, responsible for vision, is visible during eye surgery.
These visible nerves look like white threads or cords due to the myelin sheath that surrounds and insulates the nerve fibers.
