I've created a diagram which shows the relation of those elements in the rectangles to the circle. The issue is that the arrowheads all bunch up where all the lines meet at the circle, like so:

Is there anyway to amend my example below, to allow for the placement of the arrowheads to be somewhere on the line to be able to show the direction more clearly?

\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{positioning,shapes,arrows,decorations.markings}

paths/.style={<-, >=stealth'},

According to the answer here: https://tex.stackexchange.com/a/39282/120578

you can use the code :

\tikzset{-<-/.style={decoration={
  markings,
  mark=at position 0.1 with {\arrow{<}}},postaction={decorate}}}

before your tikzpicture.

Then change the line of paths/.style to :

paths/.style={-<-, >=stealth'},

it will give:
