They see biology as a series of kludges and flukes that just happened to come together. Naturally, they view the giraffe’s recurrent laryngeal nerve as an evolutionary blind alley. The nerve pointlessly got stretched. But in fact, on its long journey around the giraffe’s heart, the recurrent laryngeal nerve is hard at work.

2016-08-22 · And in a giraffe – RLN in blue, nerve path to hindfoot phalanges in red. Hollow circles are nerve cell bodies, solid lines are axons. And in the elasmosaur Hydrotherosaurus, same color scheme plus the nerve path to the tail in purple, base image from Welles (1943). That’s all for now! References. Ecker, A. 1889.

Skada på NLR ger en tydlig påverkan på stämbandens rörlighet, så kallad recurrenspares, då NLR innerverar fyra av de fem inre larynxmusklerna (Mattsson, Hydman, & Svensson, 2015). Because of multiple variations in course, the inferior laryngeal nerve shows a great variety of topographic relations to adjacent cervical structures. It may recur in the tracheoesophageal groove or anteriorly or posteriorly to it. It can pass under, over, or through the ramifications of the inferior thyroid artery.

While in humans this is a detour of mere inches, in the giraffe the nerve is around 15 feet long. Click on the link only if you agree seeing a real dissection of a giraffe.

Phylogenetisch interpretiert gilt der Nervus laryngeus recurrens als ursprünglich sechster Kiemenbogennerv.

Recurrent Laryngeal Nerve. The inferior laryngeal nerve is the motor input to all other laryngeal muscles and is primarily responsible for the temporal fine structuring of the calls (Rübsamen and Schuller, 1981).

The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles.

(de) El nervio laríngeo inferior o recurrente, del latín nervus laryngeus recurrens, es un nervio que parte del nervio vago, conduciendo impulsos motores y sensitivos, así como fibras del sistema nervioso autónomo a una porción del cuello (laringe), por debajo de las cuerdas vocales. Flag as Inappropriate Tyreoideakirurgi är förenat med risk för skada på nervus laryngeus recurrens (NLR).

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.

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.

Defechereux et al. 2000). Thus, even from a neo-Darwinian point of view, important additional functions of the Nervus laryngeus recurrens should be postulated and looked for, not to mention the topic of embryological functions and constraints. There is heaps more explaining why your position is invalid, you may want to read it, most likely not.

No two giraffes have Latin, nervus laryngeus recurrens The extreme detour of this nerve (over fifteen feet in giraffes) is cited as evidence of evolution as opposed to intelligent Giraffes are multicellular organisms. Giraffes are made up of animal cells. Unlike plant cells, animal cell do not have any vacuoles or chloroplasts or a cell wall. The Laryngeal Nerve of the Giraffe: Does it Prove Evolution?
