The term 'NERVE' can be broken down into two prefixes, 'neur' and 'neuro'. The prefix 'neur' is derived from the Greek word 'neuron', which means 'SINEW' or 'STRING'. The prefix 'neuro' is derived from the Greek word 'neuros', which means 'NERVE'. Both of these prefixes are used to describe a type of tissue that is composed of NERVE cells. This tissue is responsible for transmitting electrical signals throughout the body, allowing us to sense and respond to our environment.
