Hey Slevesque, a few points.

So it seems that it does in fact have a role in supplying parts of the heart, windpipe muscles, mucuous membranes and the esophagus.
No it doesn't. The Vagus nerve, of which the Laryngeal nerve is a part does. The Laryngeal nerve, as the name suggests, only goes to the larynx, it doesn't connect to anything else.
Can a discussion be continued based on this new information ?
It isn't exactly new, we know what the different nerve endings of the Vagus nerve connect to, and it does nothing to the argument that the Laryngeal nerve doesn't have to take that route from a design standpoint.
Watch this video of the dissection of a giraffe again, the nerve that goes down is the Vagus nerve (listen to the woman doing the dissecting, she esplains this), which "splits" at the bottom and the Laryngeal nerve is the nerve that runs right back up again. Why would it do this? It could just "split" right at the top, have the rest of the Vagus nerve go down, and have the Laryngeal nerve connect to the larynx. At least, from a design point.
Linky

While the page deals with the vagus nerve generally, it also discusses its various branches of communication severally. And slevesque's quote is specifically about the recurrent branch of the vagus nerve, it says that right there in the quote.
Yes, but isn't this supposed to be about the Laryngeal nerve? that doesn't have to be recurrent, does it? Like I said, it could "split" from the rest of the Vagus nerves at the top, and let the rest continue downward.
Or am I missing something here?
Get your sackcloth and ashes.
Gladly, I just don't seem to see where I went wrong.

The laryngeal nerve is the name for a bundle of nerve fibers, some of which terminate at the larynx and some of which don't get that far. It doesn't just designate the ones that terminate at the larynx.
You're using "laryngeal nerve" to mean the nerve fibers which do terminate at the larynx, but that's not what it means in medical terminology --- it includes those that are part of that whole bundle of nerves but which (for example) terminate at the cardiac plexus. Which slevesque's quote and link should have made clear. That was your mistake.
Aha.
Slevesque's mistake is to treat the existence of this bundle of nerves (the recurrent laryngeal nerve) as though its existence was somehow inevitable, rather than just being a term we've adopted to describe the facts as we've found them. Under that assumption there is a good reason why the recurrent laryngeal nerve should go round by the heart --- it needs to connect with the cardiac plexus. But then of course the specific nerve fibers which connect to the larynx don't need to be part of the recurrent pharyngeal nerve.
Does that straighten things out? (So to speak.)
It does, and I see where I went wrong. So, for that, I appologize. I do think however that the main point remains. The nerves that connect to the larynx do not need to go all the way down the neck.
Thanks for clearing that up.

You might be aware of it, but you don't know anything about it.
The problem is I haven't seen any books that explain the details of where the RLN came from and the probable path of how it randomly and miraculously ended up providing such a clear and obvious purpose.
And you won't find any. The main reason for that being that evolution is not a random process.
Obviously, none of you have a clue either according to your empty posts.
We explained it to you, you just ignored it.
