The superior laryngeal nerve is a branch of the vagus nerve. It arises from the middle of the inferior ganglion of vagus nerve and in its course receives a branch from the superior cervical ganglion of the sympathetic nervous system. The superior laryngeal nerve consists of two branches: the internal laryngeal nerve, which supplies sensory fibers to the laryngeal mucosa, and the external laryngeal …

The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. The extreme detour of the recurrent laryngeal nerves, about 4.6 metres (15 ft) in the case of giraffes,: 74–75 is cited as evidence of evolution, as opposed to Intelligent Design. The nerve's route would have been direct in the fish-like ancestors of modern tetrapods , traveling from the brain, past the heart, to the gills (as it does in modern fish). others about the Nervus laryngeus recurrens as a "proof" or at least indisputable evidence of the giraffe's evolution from fish (in a gradualist scenario over millions of links, of course). Markus Rammerstorfer has written a (scientifically detailed and convincing) synoptic critique on this old and, in fact, already long disproved (C)Channel4From "Inside Nature's giants"http://www.channel4.com/programmes/inside-natures-giants/4od#3072424Richard Dawkins demonstrates laryngeal nerve of t As a result the recurrent laryngeal nerve of giraffes loops under the aortic arch instead of over the arch. Offspring of giraffes that are born with a longer neck have more chances of surviving and passing on the trait because they have an easier time to access food sources in higher places and an easier time to watch out for predators. To innervate the esophagus and trachea of the giraffe and also reach its heart, the recurrent laryngeal nerve needs to be, indeed, very long.

2020-07-10 · The giraffe is a mammal known most famously for its long neck. True to biological homology, the recurrent laryngeal nerve of the giraffe also routes via the thorax and under the aortic arch, a considerable detour. While in humans this is a detour of mere inches, in the giraffe the nerve is around 15 feet long.

Einseitige Schädigungen des Nervus laryngeus recurrens – z. B. durch mechanische Schädigung bei Halsoperationen (Schilddrüsenentfernung), Entzündungen in seiner Umgebung oder des Nerven selbst – führen zu einer Lähmung oder Parese der Stimmbänder (Rekurrensparese) und damit zu einer heiseren Stimme.

However, just to refer to one possible substantial function of the Nervus laryngeus recurrens sinister during embryogenesis: “The vagus nerve in the stage 16 embryo is very large in relation to the aortic arch system. The recurrent laryngeal nerve has a greater proportion of connective tissue than other nerves, making it more resistant to 3) The giraffe has eigh t cervical vertebrae.
