Neuronal is a term that describes something related to neurons or nerve cells. There are several synonyms for this word, including neuronal, neural, nervous, dendritic, and synaptic. The term "neural" is a more general term that refers to the entire nervous system, while "nervous" describes the function of neurons in transmitting signals between different parts of the body. "Dendritic" refers specifically to the branch-like projections that neurons use to communicate with each other, and "synaptic" describes the space between neurons where these communication signals are passed. All of these words can be used to describe different aspects of the complex workings of the nervous system.
