Sciatic nerve anatomy

The anatomy of the sciatic nerve!
From the lumbosacral plexus in the lower back and sacrum, through the greater sciatic foramen, into the gluteal region, posterior thigh, splitting into tibial and common fibular nerves that run into the calf, anterior and lateral compartments of the leg and then into the foot. Muscles and skin.

Im done with Anatomy and really loved the class but I miss watching these videos. So I will watch for fun.

[@keegancan]

Do you remember everything from anatomy?

[@josetrujillo738]

No question one of my favorite teachers to watch on KZbin! I could also say you are my favorite teacher to watch no question, in many ways, for many reason! No other teacher quite like you on KZbin! You make me love to learn more! Thank You Sam Webster! I wish you many, many beautiful blessings always in your life; and for your family and loved ones!

Give this man a Nobel prize. Sweden would be so proud.

[@MrMrAzad]

why sweden. isnt he from U.K.

[@kerithj6919]

Thank you for the helpful lesson. Literally everyday I see patients with pain related to the sciatic nerve. You did a very fine job describing how symptoms could be of lumbar spine origin or compression from deep gluteal muscles. I would also add that sacroiliac joint dysfunction can refer pain to the area as well. I learn so much from you and consider you my virtual coach.

[@user-cd6iv3nf3d]

I'm really happy to show the video. I'm a physical therapist in Korea. But my head was massed up because the structure of lumbar to lower leg is hard to understand and don't know how to link the therapeutic methods to anatomy. But I subscribe your KZbin, I queit understand why the anatomy is important and can joint therapy with anatomy. I was blessed due to finding the KZbin channel. Thank you and have a great day.

💎 Gem - The Sciatic nerve innovates the posterior thigh and everything below the knee. I will remember that! Thanks so much again for your entertaining and informative presentation.

Being an engineer and having had a successful L5-S1 discectomy.... and three bouts of bulging disk sciatica over the past 12 years, I’m VERY interested in this anatomy, because it really helps to understand which stretches, McKenzie methods, sleeping positions, etc work and why they work. What I can’t seem to find out, and I think it might be very important, is how the sensory and motor neurons are separated in the sciatic nerve bundle (especially as they pass by the pinch points in the spine). I’m suspicious that the motor neurons might be in the center, surrounded (protected) by the sensory neurons... with the idea that maybe the motor neurons are more important to survival than the sensory neurons. If this is true, then it might mean that if your sciatica symptoms are numbness (only), or pain (only), then the pinch is putting less pressure on the nerve than if you have loss of motor function (pinching so hard that even the center neurons are being pinched). This would help us to monitor the progress of our treatment. Do you know how the sensory and motor neurons are separated?

Wish I had known about this guy during my dissection days in med school. Absolutely superlative, especially for someone like me who struggles with key anatomy concepts which require good spatial orientation. Written text or images on a page are simply no substitute.

[@EN-ks1vt]

I highly recommend patients review the appropriate videos as well. Sam's simple and conversational tone can unravel many mysteries AND help them communicate effectively with their provider. Excellent work sir. Thank you.

[@nb2028]

Brilliant Sam! Thanks to your upper limbs for holding up the model for us.

[@marija0001]

This was enormously helpfull!! Thank You so much for this and other lectures!!! Greetings from Serbia!!!

[@monica11119]

Excellent video! I love Anatomy; you are the coolest teacher ever Sam! Kind regards.

[@andrianahoward521]

Thank you for this video! I have sciatic pain but never really understood what was going on. It’s interesting to hear what the nerve actually is and how it can cause pain 👍🏽 Awesome video!

[@roland.j.ruttledge]

Fantastic. Exquisitely illustrated, many thanks.

[@kareemelsayed5208]

Convenient timing very surprisingly. Needed this so much. Thank you

[@faithabovefear5737]

Best teaching skills👍. More power to you. ✨

[@fakename3042]

I am 31 years into a manual therapy career and would sign up for anatomy courses if you have organized distance learning. I can follow and understand the subject material very well. Great teaching!

[@CARRJ142]

Another great video.

[@vincentmonet6172]

Impeccable teaching 🖖

[@trulyasleep294]

absolutely love this guy

[@ancamuresan8765]

Thank you! Great anatomy lesson!

[@Mike-hw5jp]

Sam your videos absolutely fly by. Where did that 20 minutes go? I am so grateful to have access to these and to someone so obviously passionate about their job. I am currently suffering from some deep gluteal pain. I'm pretty convinced its either sciatic or gluteal nerve compression or entrapment but nobody can figure it out so far. Had this issue on the opposite side about 4 years ago. Piriformis injection solved the symptoms but I never got an answer as to why it happened. I must solve this once and for all and get my life back

[@Kriti2024]

Found the cause of your pain, Mike?

[@filipristovski7081]

Great explanation, just keep going with these amaizing videos. You got our support :D

[@elmanzanito6244]

[@saumyalandge7349]

Thank you so much

[@anagalic-fz9uo]

thank you sir!

[@sunseeker4775]

Great explanation, thank you. Question: why serious pain, only when lying down on either side and at no other time? Can't find the answer to this and it's been happening for at least 9 months.

[@RichArtLove]

Brilliant! Big Thanks From Here On The Beaches Of Southern California...

[@robertodejesus2529]

Thank you very educational

[@giovannacolone]

Since watching your videos, I am a way better massage therapist. It excites me to learn. And yes, you look like house but prettier. 😃

[@user-kr6uw8pf2t]

thank you 🤩👍👍

[@sonali.gokani]

When sitting cross legged on the floor, afyer 15mins i feel loud pressure on the nerve below buttocks which numbs the leg down till the toes... i also feel tension deep behind the knee in certain stretching postures... what should I do to fix this please?

[@lesatanatomy5146]

Nice Nice! what is the best anatomy book for you sir?

[@Noway673]

That made alot of sense! When lay down I don't feel no pain in my back and sciatic pain until I stand up and about less than a minute I feel the tingling and it travels all through my left side and the numbness appear along side and the pain is felt on my butt.I just want this thing to heal so I can go back out side again it's been 6wks and I still have this.I don't have any back pain and I can get up with ease and can walk around but only about 7 to 10minutes and the pain comes back and have lay down and massage my buttocks to relieve the pain.But when lay down it like I don't have no problems as a normal feeling.

[@ThokoDlamini-fp8uv]

Why does it cause pain - what is the permanent solution for THIS,?

[@noormuhammadkhan4135]

Thanks you

[@keegancan]

It looks like sura means calf. Does the sural nerve serve the calf?

[@Montypython7777]

I'm a simple man. I see "anatomy", I click!

[@ahlmakkah7030]

How can one get rid of that pinching pain? How to actually address that problem where it starts from but the pain runs down the hip bone and the whole leg. Pls help!

[@francimasaza8749]

[@PikesCore24]

This is unrelated to video, but what does "semi" mean in the semispinalis? I can't think of any other place in anatomy where I see the word "semi".

[@someone-yj2im]

Usually semi means half. It could be that it is called semispinalis because it is about half the length of the spinalis muscle... Just my guess tho

[@user-nt1yw1dw5c]

Good

[@Noway673]

I wish this guy can come up with an solution to this because I did all these Body Mechanic exercise and it did work far as my back pain because that was my big problem!

[@furbelox5821]

You are 24hr too late with this 😂 Got asked some of this yesterday in my oral USMLE 1 (i’m from germany)

[@alsharabyalsharaby1483]

please Dr Sam, we need to know that the muscles of forearm attachments for? it means that we want more explaining for forearm muscles Thank you Dr Sam

[@someone-yj2im]

Try checking AnatomyZone for that. He explains them in detail with origins and insertions

[@jamesb7120]

Remember hands are connected to heart :)

[@chriswalsh9334]

Thanks very much. Really informative. But something I still don't understand. Over the years I have had a number of cortisone injections for elbow and sciatica issues. I have responded very well to the treatment, but of course it wears off after a couple of years. On the basis of issues indicated by my X-rays my last sciatica treatment in early 21 was to the left side L4 and L5 vertebrae. But I am now starting get some minor discomfort down my left buttock and some significant discomfort on the outside of the lower calf and shin, an ache when its under load and I'm upright and a slight burning sensation when sitting, worse at night. It seems to me that rather than forming one nerve body, like say a river that has tributories flowing off it that the sciatic nerve is more like a collection of wires that sort of join together to run down the buttock and thigh but then break away from the main path to service particular muscles in the leg. I'm thinking that if I opt for another cortisone shot then the target should be L5. I am not asking for a diagnosis, just asking if you feel my understanding of the sciatic nerve is correct? Thanks Chris

[@jobbygerm2706]

I know this is a tad late here, and you've likely sought treatment. If you get familiar with the dermatomes it'll clear your understanding up from what nerve root your pain is coming from. When you say 'the target should be L5' then that could refer to L5/L4 OR L5/S1. Remember that the cortisone is injected around the nerve roots (where the nerve) branch off in and from the vertebrae. So, from what you've said it looks more likely to be L5/S1 involvement. There are great 3D interactive models on the internet those married up with knowledge of dermatomes will be far more clarifying you. However, large nerves like these are bundles of bundles of neurons (wires) and maybe the idea that they are single bodies of water splitting off isn't suitably reflective

Anatomy is kinda hard if you don't memorize each bone and its name, it is complicated and I'm doing my best to learn it. From High school ''last year''

[@xanamata5386]

there was a video on youtube that someone rip the whole nerve out of a dead body .

[@muskangaba4341]

Currently lower limb is going on and this shows up haha
