Mollusque, you're reminding me of one of my freelance gigs. I plow through that kind of writing constantly. But I have to admit that I've never heard ocular muscles compared to reins of a pair of horses. :-)
The dextroducting innervation acts equally upon the right external rectus and the left internal rectus. The laevoducting innervation acts equally upon the left external rectus and the right internal rectus. It will be seen, therefore, that the arrangement is very much like that of the reins of a pair of horses....
