Describe the structure and functions of the neuron

I don't know much but i think that the structure is the things you can see and the functions are like the axons and dendrites that is working through it. the signals are the functions and the structures are the axons and dendrites because you can physically see them. 

Americans often speak of their country as one of several large regions.  these regions are cultural units rather than governmental units --  formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share. what makes one region different from another? a region's multicultural heritage as well as distinct demographic characteristics like age and occupation make regions different and special. within several regions, language is used differently and there are strong dialects. there are also differences in outlook and attitude based on geography.
