Neurology | Spinal Cord Meninges

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds!
In this lecture Professor Zach Murphy will present on several concepts related to the spinal cord meninges. We hope you enjoy this lecture and be sure to support us below!
Correction at 5:31 - There is only one layer of the SPINAL Dura Mater. This is different in comparison to the Dura Mater in the brain which has a two layers: an outer perisoteal layer and an inner meningeal layer. Thanks Ninja Nerds!

[@DrmaryamPT10]

Thank you sir Sir it means dura inner layer is present just for an example ....and between bony layer and dura (1) layers there is epidural space ?

[@ogheneroemavwodia6698]

Thanks for the amendment

[@vincentcyrilliansantoso9858]

Thank you Professor, Does that mean that in the spinal, the epidural space is only a potential space (not really there) and in the brain, epidural space is a real space?

[@Radjehuty]

​@@vincentcyrilliansantoso9858no there really is an epidural space superficial to the dura in the spinal cord. It contains fat and vascular tissue. The layer superficial to the epidural space in the spinal cord would be the ligamentum flavum posteriorly and the posterior longitudinal ligament anteriorly to the spinal cord.

There’s only one layer of duramater in the spinal cord. The outer layer of dura in the cranium doesn’t travel into the spinal cord it’s continuous with periosteum of skull bones at the foramina. Correction at 5:31

[@NinjaNerdOfficial]

Thanks for pointing that out! You are absolutely correct!

[@alishaakhani1016]

From India! Please please do one on EEG!! You'll explain it so well I can't wait 🤗🤗

My boyfriend stumbled across one of your videos a few months back. He's a paramedic/Fire/ future nurse and Dr. He absolutely LOVES you and how WELL you teach. As do I. YOU'RE ridiculously SMART. YOU ROCK. ZACH.

[@anniesiev7479]

I'm wondering why I'm paying so much for school when I could be learning from you. Your videos are so much better than the dreadful lectures my current professor provides. Thank you!

[@Emilio77able]

Loved the explanation. Simple, clear yet captivating as always. You do a fantastic job Zack, and the entire team behind you. Can't thank you enough!

[@DrEldersAnatomyChannel]

I love the way this is explained in such a simple manner. I really appreciate this as a review of material

[@Leeus13]

Why is this not being shown in medical school curriculums!?! Your videos are amazing and have helped me tremendously throughout the year! Can't wait to see more!

[@MrHuddo]

Awesome vid once again, Ninja. This format where you use a familiar medical exam (lumbar puncture in this case) to explain the anatomy is awesome! Please do more like this.

[@dee8168]

Sir, you have saved my life by uploading your videos. Thank you and more power to you and to the people behind this channel!

[@vinnymurphy1299]

Good to see you back zach! I'm taking a year out of medicine this year to get another degree, but I'll be able to keep my knowledge up to scratch with your great videos!

[@jennifercleveland2572]

Keeps getting better. I have 3 symptomatic Tarlov cysts at s2. No neurosurgeon in my city will not see me so I have not been able to ask any questions, your videos are the only way I can possibly understand what might be happening to me. Thank you

[@josetrujillo738]

When you think of “mother”(Mater), you may also think of “protecter”; so “soft protector”, “hard protecter”, “spider-like protecter”; that’s what I imagine.- thank you for teaching us Ninja Nerds!

[@Theslayqueen123]

WE ALL, ABSOLUTELLY LOVE YOUR VIDEOS AND LOVE YOU TOO. YOU ARE THE NIAGRA FALLS OF MEDICAL KNOWLEDGE. GOD BLESS YOU FOREVER AND FOREVER.

[@josephreo4209]

Thanks Zach. You are looking so healthy. Happy for you. Hope to see you at Giant in Hellertown soon.

[@samuelpraxedesvillanueva8241]

Isn't the periosteal layer only present in the skull? Only the meningeal layer of the dura mater extends to the spine correct me if I'm wrong.

[@muskandeshwal9299]

Amazing lecture as always ❤️

[@medicalmegamind4884]

Great video Sir! Zac Murphy is my Inspiration 😊

[@thedesidoc1377]

U make any topic too much palatable , that's what I like about this channel .

[@tonmoynath4332]

Thank you so much Sir♥️ Really helpful ....love From India ♥️

[@khushipatel4998]

love ur videos ...thankyou for this....just one thing.....the spinal dura mater does not have an outer endosteal/periosteal layer unlike the cranial dura

[@sagnikdas4168]

This video is so helpful........plz make some video on abdomen ..... like peritoneum , perineum, liver and portal circulation...

[@emanuelemerlo2717]

I have a doubt. You say that the epidural space is between the 2 layers of dura mater. So, if It is "epi-dural", It means epi=Upon; It is upon dura mater and It can not be between its 2 layers. The definition that you give here, actually is in contrast with the definition of epidural space in the skull, where It Is between periosteal layer of dura mater and the bone. So I do not know why also some Books and Wikipedia and you say that definition. It does not make sense. When you speak about epidural hematoma, you see blood between the bone and dura mater in the epidural space in the skull. How can you give 2 different meanings about the location of the epidural space? I need an explanation. Thanks

[@linahan1634]

Now I have the same question

[@samiullahsyed7545]

Isn't the meninges of the Spinal Cord and Brain slightly different? Like I'm pretty sure that the periosteal layer of the dura mater doesnt exist in the spinal cord(I think I saw it on NCBI).

[@emanuelemerlo2717]

@@samiullahsyed7545 I read your definition only in one book. My books and professors say that dura does exist in spinal cord. I do not know the truth, but for my exam I am obliged to say that.

[@DrmaryamPT10]

Same question kindly explain

[@emanuelemerlo2717]

@@DrmaryamPT10 we are all waiting for the truth ahahah 💙

[@Assdp00]

Correct me if I'm mistaken, but doesn't the spinal cord dura mater have no periosteal layer ?

[@shanartz8152]

Agree.. sp cord don't have periosteal layer

[@dailydoseofmedicinee]

The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. The pia mater is the meningeal envelope that firmly adheres to the surface of the brain and spinal cord.👍

[@moonay18]

thank you for your job, it's awesome!

[@user-jr9py3lj4b]

Epidural space is not inbetween 2 layer of duramater! It is intradural space! Epidural space is right beneath of the ligament flavum when punctured! By the way l love all of your lectures ! From south Korea

[@legendarybalasik3155]

Awesome lectures

Great lecture zach. Can you make some video of the cistern of brain or vein drainage of brain?

[@user-tj1ky2cr4e]

Isnt the epidural space supposed be to superficial to peroisteal layer of dura mater hence the name epidural, ie between ligamentum flavum and peroisteal layer of dura mater?

[@linahan1634]

Epidural space in FA is between ligamentum flavum and dura mater

[@leelakrishan7453]

I like the way you teach, keep it up 👍🏻

[@mercylanogwa2410]

Thanks so much Keep up the good work

[@magezitom2217]

Is the the outer periosteal layer of the dural mater also part of the spinal cord?

Is it possible for the meninges to relax because of any relaxation technique?

small correction ninja nerds that is epidural space is space between dura mater and vertebrae, not between two layers of dura mater and also their is no two layers of dura mater present in spinal cord

[@kacinichols5827]

Amazing!

[@surajchaudhary290]

Does Outer dura mater(Endosteal layer) run throughout Spinal Cord?

[@emanuelemerlo2717]

It depends on the book where you study at. Some say "two layers of dura in the spinal cord", others say "one layer". We have to do an autopsy, in order to discover the truth 😅

[@sarablackwolfdancer9359]

I know this is really specific, but could you address how inflammation in the meninges would look? Lumbar punctures can cause inflammation in the meninges, so it's relevant, but it's a little arcane.

[@afnanahmedkhan3862]

space between outer deura matter and ligamentum flauum ???

what is the difference between cranial vs spinal meninges

Shouldn't the video itself be amended so one does not have to rely on catching the correction below concerning only one layer of spinal dura mater?
