Accepted Answer

Neuroplasty is the surgical repair of a nerve or nerves. Neurolysis is the surgical procedure in which adhesions (bands of scar tissue) that have developed between a nerve and surrounding tissue are broken down. Neuropathy is a disorder that affects the nerves responsible for transmitting signals throughout the body. Neurosclerosis is a condition in which the nervous tissue is hardened or undergoes induration.
