Anatomy of the Spine | Model

Ninja Nerds!

Join us in this lecture where Professor Zach Murphy will be discussing the anatomy of the spine through the use of a model. The structures we discuss are the spinal dura mater, the arachnoid mater, pia mater, epidural space, dorsal root ganglion, and the horns of spinal cord and white columns. We hope you enjoy this lecture and be sure to support us below!

Correction: 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. Another important note is that cell bodies are not myelinated, only axons are myelinated. Thanks!

Re-watching this entire playlist as a refresher before starting my first PA job in neurosurgery! I've recommended these videos to all of my new grad neurosurgery friends!
You're a lifesaver!

Anterior white column --- crude touch and pressure
Lateral white column --- pain and temperature
Dorsal white column --- fine touch and proprioception

Layers from outside to inside
Dura Mater (periosteal layer)
Epidural Space with blood vessels and fat
Dura Mater (meningeal layer)
Subdural space with bridging veins
Arachnoid Mater
Sub arachnoid space with CSF
Pia Mater directly clinging to spinal cord

You are literally saving us during Quarantine! Love the content!

The spinal cord dura mater has no periosteal layer. The epidural space is found between the dura mater and the ligamentum flava

[ronaldbenjamin]

Love the detail. Just need descriptions on the video itself i.e. each part pointed to. Thanks!!

[shaayla]

you don't understand how much this video helped!!!

[arginine]

Even u haven't ever thought that your lectures would be life savior in covid period 😅 anyway great content sir!!!🤗🙏

[hiraisani]

Thanks to your videos i got through my 1 semester! Hoping you’ll save my ass in semester 2 too ❤️😂

[gamerguyriyad]

You teach better than nearly every single lecturer at the University of the West Indies, St. Augustine Medical School. Yes, I said it.

[noorhasham]

Sir plz upload a video on spinal reflexes in physiology...

[salam]

thank u so much and thanks for the one who added the Eng subtitles ^-^

[etomidateem]

3:22 epidural space. Thanks for the video :)

[aishahalmoqary]

Okay that’s weird but your voice makes me feel comfortable I mean I can sleep listening to your voice 😭😂

[amanazulaika]

Can you please make a video on Basal ganglia, Limbic system, Thalamus, Muscle spindle, and Golgi tendon organ and spinal reflexes.
Thank you guys, you are real life savers

[mruganibhagvawala]

Best videos ! Can you plz make playlist pf neurology n add all the neuroanatomy videos in that playlist

Is there conflicting information in anatomy about the spinal cord meninges? As far as I could find, there is only 1 layer of dura in the spinal column and 2 around the brain. The layer labeled "5" superficial to the epidural space should be the ligamentum flavum and anteriorly on the posterior aspect of the vertebral body, the posterior longitudinal ligament. I don't think naming conventions would call this an epidural space if it was really intermediate to 2 layers of dura.

3:34 Do I have color blindness or there is really no blue?

[friedangotipeni]

PLEASE MAKE A VIDEO ABOUT THE ANATOMY AND PHYSIOLOGY OF THE CEREBRAL CORTEX AND ITS CORTICAL FUNCTIONAL AREAS.

[The_Argent_Inferno]

Amazing video as always, thank you so much

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
