Spinal Cord Injury, Motor Neurons, and Reflexes

In this video, Dr Mike explains how motor pathways travel from the brain and down the spinal cord to the muscle. He explains how reflexes work and what happens in upper motor neuron and lower motor neuron injuries.

Thank you very much doctor, you were able to explain an incomprehensible 2 hour lecture in 8 minutes completely understandable lecture, I think our professor needs to watch your videos too

[@alqudsislam6819]

this is the first time in my medical life i understand UMN and LMN clearfully
thank you a lot

[@leah8613]

Thank you so much! Neurology isn't my strongest subject and I find it quite overwhelming. You've just explained the concept of UMN and LMN lesions in such a simple way and I finally understand, woo! Thanks again. Take care

[@beaalmeida8066]

The HOURS i spent trying to understand this concept and in 8 minutes it just makes sense. Wow. Thank you so much

[@chiquelemon]

[@Fatima-dp8zq]

Thank you so much 👍🏻

[@Hellastorytella]

This video is amazing but one thing: perhaps moving the drawing of the leg to midline of the cerebrum to coincide with the homunculus would help with understanding. Amazing job!

[@sarvinozakhadova]

Thank you so much was very helpful 👌👌☺️

[@89jyothilekshmim96]

Good presentation, though muscle power can be also severely decreased in upper motor neuron lesions.

[@dr.ameze_osayande]

[@bmfsnc8466]

My neurology of communication class would be a lost cause with out Dr. Matt

[@pm012mymd2]

your the best

[@NoSleepFromBrooklynAdventures]

I wonder if my cranial cervical instability (due to Ehlers Danlos, which is now fused) is what brought on Dystonia (episodic but generalized) for me...and would this qualify as upper motor neuron or spinal cord injury?

[@kejuantaylor21]

What's the best way to reverse this after a spinal cord injury.. what diet and herbs/exercise..? My injury level c7 c6 incomplete My spasms do pretty good after a good stretch. Any advice will be great 👍🏾

[@bramverlangen1906]

Sir, could you explain why antigravity muscles (flexors for the upper extremity and extensors for the LE) are more affected in (not completely paralytic) UMN lesions?
I read it has to do with inhibitory pathways, but unfortunately I do not fully understand it!

[@davidfriedlander9868]

I have a question regarding hypertonia and hyper-reflexia (5:00 of video). If someone has an UMN lesion, could the hypertonia/hyperreflexia also be clonis?

[@PoleiceCidcorn]

Dr Matt, so hyperreflexia with flaccid limbs? UMN & LMN with problems from disinhibition.
Ie a patient with flaccid limbs will move the limbs with stimulation to just the hamstrings.

[@everitadave]

my daughter is tipotoing and there is no real diagnosis, also inwardly turned left leg. she is 15 now. do you have any suggestion?

[@shereengoh4123]

Dr.Mike, I have one question.... why isit LMN lesion in the arm and UMN lesion in leg when there is Cervical injury?
I am very blur about this. 😢

[@Rrrrcc4666]

At the level of lesion it behaves as LMN and below the the level of Injusry is UMN. So you you will have to see which level and which muscles are getting involved and according to that LMN lesion will be flaccid and UMN lesion is spastic.

[@RealFredbaby]

Epic

[@miguelbertonatti]

💪🏻

[@Angelo-uo2gj]

What about people who have a flaccid hemiparesis from a stroke? Why do they present like that?

[@hadeel.1751]

that's amazing 🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩 i love you

[@zainabdeen8972]

Thank you for your effort, but I would like you to be a little slower in explaining because English is not my original language .. Thank you again
