Sammenskrivning af simpel fuktion?

Jeg har:

function arrowA() {
  document.getElementById('arrowA').innerHTML = "<img src='images/sitegraphics/reddot.gif' alt='Menu marker' border='0'>";
  document.getElementById('arrowB').innerHTML = "";
  document.getElementById('arrowC').innerHTML = "";
  document.getElementById('arrowD').innerHTML = "";
  document.getElementById('arrowE').innerHTML = "";
  document.getElementById('arrowF').innerHTML = "";
  document.getElementById('arrowG').innerHTML = "";
  document.getElementById('arrowH').innerHTML = "";
}

function arrowB() {
  document.getElementById('arrowA').innerHTML = "";
  document.getElementById('arrowB').innerHTML = "<img src='images/sitegraphics/reddot.gif' alt='Menu marker' border='0'>";
  document.getElementById('arrowC').innerHTML = "";
  document.getElementById('arrowD').innerHTML = "";
  document.getElementById('arrowE').innerHTML = "";
  document.getElementById('arrowF').innerHTML = "";
  document.getElementById('arrowG').innerHTML = "";
  document.getElementById('arrowH').innerHTML = "";
}

function arrowC() { ...
function arrowD() { ...
function arrowE() { ...
function arrowF() { ...
function arrowG() { ...
function arrowH() { ...

Det virker storartet, men der må være en måde, at skrive det kortere på?
