The Recurrent Laryngeal Nerve: Afternoon Anatomy #1

What anatomical features do we have in common with other animals? When we compare these features across species, what do they tell us about ourselves? These are but a few of the driving questions behind this video series, which begins here with a look at the recurrent laryngeal nerve in humans and giraffes. ==================== If you enjoyed this video, please subscribe! ==================== Extra notes on anatomy: *The recurrent laryngeal nerve is a branch of cranial nerve X, otherwise known as the vagus nerve. This means that the descending portion of the featured nerve belongs to the vagus, and the ascending portion is the recurrent laryngeal nerve. *The vagus nerve exists within the body as a pair, one on the right side and the other on the left. This means that there is also a right and left recurrent laryngeal nerve. While this video features only the left nerve, the right is also known to take a slightly less sizable detour. *This video is not making the assertion that fish have a larynx similar to that of humans or giraffes. Fish possess gills and developmental gill arches from which the larynxes of tetrapods were derived. ==================== Extra notes on ancillary content: *I understand that much of the death imposed upon giraffes is not due to poaching, but is rather due to hunting (bush meat) and habitat loss associated with farming. I would never suggest that people in such an impoverished part of the world not utilize whatever food sources possible to survive, which is why the distinction between hunting and poaching is required. My condemnation is aimed specifically at poaching and foreign exploitation of this region. ==================== Special Thanks to: Neil Shubin, author of Your Inner Fish. Richard Dawkins, author of The Blind Watchmaker. It is from these books that I found my inspiration, and I would recommend them to anyone interested in the content of this video.
