How does sense-perception work?

I need these questions answered.

1.  How are psyche [soul? mind?] and body related?

2.  Aristotle discusses six faculties or powers [dynamics] of the psyche. List and define them, in ascending order of rarity. {If you only find five faculties, just go with them.}

3.  How does sense-perception work?

4.  How are perception, imagination, and opinion or judgment distinguished?
