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.

I think your absolutely amazing Mr Webster..... and your videos have been a life saver more than you can imagine. Keep up the good work ❤️
Passed my MRCS DOHNS the other month Sam. Can I please thank you for your anatomy content - they were invaluable in my preparation. Keep up the good work! More Head + Neck content please!
Your 15min videos do more for me than a whole day of lectures by my teachers.. You are the absolute best 😍 thank you!
thank you so much .you are the best teacher and special thanks for noted in surgery .
I have been without a voice for the past 3 months because of lung cancer… very interesting explanation
Dr. Sam you are such a lifesaver👍💯....you made anatomy interesting to me💕
I'm doing a module on the regional anatomy of the thorax and your videos were SUPER useful to me
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.
I was searching for this particular topic 😂 What a timing 😊 Thank u soooooo much 💖
Thanks again! These videos are great and so helpful!!!!
You are a great teacher
I’m watching from the University of Nigeria ❤
👏👏👌U R EPIC..Dr. House..love u 👏😊
Brilliant and adorable❤️❤️
thankyou sirrrr WE LOVE YOU !!!!
hi Sam just wondering do you feel trauma to a rib could cause laryngeal nerve damage?
You rock :")
thank youuuuuuuuuu
Sam I think I got injured in a nerve that passes in the right side of waistline which nerve I don’t know...Im sure you know...I got symptoms of it 😔 great vids thanks 🙏 see you soon.
this proves evolution over design
Very well done and very interesting. Does this nerve innervate ONLY the larynx?
Is the vagus nerve next then? In the "fun with nerves" series?
Sir it's very confusing about the relations of vertebrae with the organs and position of parts related with the specific vertebrae. Can you please make a video about what parts are related to each specific vertebrae?
Love U ❤️
Sir, in the condition of Dextrocardia, Is the left recurrent laryngeal nerve situated on the right side and right to the left???

I think I see what you mean, and the short answer is, "yes".

It is the phrenic nerve connected with the pancreas?

No. The vagus nerve carries parasympathetic innervation to abdominal organs.
he really looks like doctor house, my god
I hope one day i meet u ...u r ♥️sir
"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?
You're so cute 😻
