Recurrent laryngeal nerve

We looked at the phrenic nerve last week. You know what's near the phrenic nerve? The recurrent laryngeal nerve, that's what. And lots of other stuff. But let's have a look at the recurrent laryngeal nerve as it's a fun one: a branch of a cranial nerve that runs to the larynx but dips all the way down into the thorax first.
What does it do? What happens if it is injured? What is its route down into the chest and back up again? How might it be damaged or compressed? What are the embryological (and maybe evolutionary) reasons for this anatomy? Let's discuss.

    Brilliant work with excellent models and explanations! I would just like to add that recurrent laryngeal nerve's function (clinically) is to ABduct vocal cords (not involved with the tensor muscle, cricothyroid, in charge of ADduction). So a unilateral injury does cause hoarseness, but bilateral injury (or nerve blockade) can cause stridor or airway obstruction, making it even difficult to intubate a patient since vocal cords could potentially be closed. Such complication would require an immediate surgical airway.

    "The most logical reason for this design is that it is due to developmental constraints. Embryologist Professor Erich Blechschmidt wrote that the recurrent laryngeal nerve’s seemingly poor design in adults is due to the “necessary consequences of developmental dynamics and are not to be interpreted … as historical carryovers” from evolution. Human-designed devices, such as radios and computers, do not need to function until their assembly is complete. By contrast, living organisms must function to a high degree in order to thrive during every developmental stage...". @t. put this in references please.

    I mean Erich Blechschmidt died in 1992, so his opinion is not very recent, and more importantly is not the consensus, so why should he put this old fringe opinion in the description?
