A type of medical operation that involves treating or repairing parts of the nervous system, including the brain, spinal cord, and nerves.
The patient underwent neurosurgery to remove a tumor from his brain.
Neurosurgery → It is formed from "neuro-" (from Greek "neuron", meaning nerve) and "surgery" (from Old French "chirurgie", meaning the work of a surgeon). The word "neurosurgery" refers to the surgical treatment of conditions related to the nervous system, particularly the brain and spinal cord.
Think of 'nerve' ('neuro-') and the 'work of a surgeon' ('surgery') to remember that neurosurgery is the surgical treatment involving nerves.
