The term “neuro” relates to which body part?

The prefix “neuro-” comes from the Greek word neuron, meaning nerve. It refers to the nervous system, including the brain, spinal cord, and network of peripheral nerves that transmit signals throughout the body. Medical terms like neurology (study of the nervous system), neurosurgery (surgical treatment of nerve or brain disorders), and neurotransmitter (chemical messengers between nerve cells) use this prefix. The nervous system controls voluntary and involuntary functions, such as movement, sensation, thought, and reflexes. Disorders like neuropathy, Alzheimer’s, or Parkinson’s disease are neurological in nature.
