Medial medullary syndrome-
Anterior spinal artery.
Hypoglossal nucleus- i/l tongue deviation.
Medial leminisus-c/l loss of position, proprioception and fine discriminative touch.
Corticospinal tract- c/l weakness.
Lateral medullary syndrome-
PICA
Medial and inferior vestibular nuclei- vertigo,nausea, vomiting.
Cochlear nuclei-unilateral sensory deafness.
Descending sympathetic tract-Horner's syndrome
Ptosis
Myosis
Anhydrosis.
Spinal NUCLEUS and tract-loss of pain temp.of face
Nucleus ambiguous- I/l loss of soft palate.
Dysphagia
Dysphonia.
Spinal leminisus-c/l loss of pain and touch.
Inferior cerebellar peduncle-i/l ataxia.
Thank you sir
Hey
Just a doubt why I/L loss of Pain touch temp in lateral medullary syndrome?
Fibres of P,T,T decussate in spinal cord only should it not be Contralateral?
Pls do reply!
SUCH A BLESSING TO MEDICAL STUDENTS .CANT EXPLAIN HOW GRATEFUL I AM TO FIND U R CHANNEL
i guess Im asking the wrong place but does anyone know a way to get back into an instagram account??
I was stupid lost the password. I love any assistance you can give me!
@@rockyjudson799 come on bro
My mom is 82 and after passing out from choking on a large pill… she went from fully independent living to the local hospital with no ability to swallow and vertigo. Amazing it wasn’t worse … after watching your video I can really appreciate the amazing abilities of the medulla oblongata/brain stem. Haven’t had Anatomy and Physiology since the early 90’s but always enjoyed understanding how it all works.
I hope neuroplasicity is a real thing and my mom gets the right therapy to become 100% again! Thank you again.. Great vid
Best teacher in the world
I am a proud member of Ninja Nerds and paid for my subscription! You are amazing! I did not think you would make these lesions so easy to understand! God Bless you
You are amazing Sir . I found your channel a week ago and I am so addicted to your videos. I had lost all hopes of understanding physiology , it was your videos that brought confidence in me . Thank you so much . You have been doing a great job ❤️❤️❤️
Just amazing
M truly impressed... How come someone didn't suggest me this channel all these years...thank u so much for ur videos... U r in the top list of all those medical teachers... 🙏
Ur videos are just sooo good and elaborated that I won't be possible to make my concept of medicine without these... thank you a trillions times
Watched these as a physical therapy student and now watching still as a physical therapist to study up on patient cases and apply to real world practice. Y’all rock! Been watching for 4 years now.
So nice to have a picture with excellent easy to follow explanation of my new life. I am 3 yrs post VAD with stroke resulted with Wallenberg Syndrome (Lateral Medullary Syndrome). Thank you. Only wish there was a fix. Keeping hope!
How are you doing now? I am fairly new to stroke world, but I also had VAD + LMS...
@@Chiboza Life is definitely different these days with balance and visual issues being the constant daily troublesome areas. But life is good. Heck, could be much worse. I continue with physical therapy. They kick my bootie! I need it. Did you join the Wallenberg group on Facebook? This group has been good for me. Knowing we are not alone and have so many commonalities yet each has their own intricacies. The medical information has been limited. So having this group available has been very beneficial (hearing from the people that are living with this from around the world of all ages). Thank you for reaching out to me. Never give up. Small gains continue - even 4 years post.
Thank you so much for making this video! Your patients are extremely lucky to have you as their provider.
U saved me from getting frustrated. Ur lectures are so clear. Thank u so much ❤️
You Rock, I play your videos for my 9th graders. They be rocking the vernacular!
You're the embodiment of Knowledge deliverance 🔥😌
I have no words for how beautifully you explain❤️......thank you so much
PGY1 Psychiatry Resident and found this extremely helpful
Dude! I always knew your video for studying for the MCAT, but when I was reading the PCOM student stories and saw you there, I was amazed! It totally explains why you're so knowledgeable. You're so cool
Great job Prof Zach(and by extension the entire team)👍👍
I would like to add:
Yes,the anterior spinothalamic tract joins the lateral spinothalamic tract forming the spinal lemniscus at some point in the rostral part of the ventrolateral part of the medulla but in lateral medulla syndrome,it is the:
▪️Lateral spinothalamic tract that gets affected(likely due to its lateral position) thus resulting in loss of pain and temperature in the trunk and limbs(i.e because of the somatropic organization)
▪️There is also loss of pain and temperature on the face( this is one is ipsilateral) as the Trigeminal nerve also gets affected.Affectation of the latter could also result in trismus(due to hyper contraction).
God has sent us his man to end our suffering and misery.
This man must be protected for the betterment of Mankind ❤.
The way u explained the brainstem strokes has finally made me understand it completely and really given me a sense of confidence. Lateral medullary syndrome has such a wide variety of presentations but with this i think i understand why its soo important for exams as soo many nuclei are involved and hence an exam fav.
YOU ARE AN ABSOLUTE LEGEND BIG MAN!!
CAN NEVER THANK YOU ENOUGH. SO GRATEFUL FOR YOU!!!!
This is truly the most informative lecture in the field of neuroanatomy. thank you
All the flowers 💐 for the best teacher.
Love the way u clearly teaches everything.
May you gain all the merits and the blessing.
Keep enlightening us.

Your videos are so helpful for me. Thank you.
This was an amazing illustration❤️❤️❤️❤️
you are literally saving my life ! THANK YOU
Same here
Zac i really appretiate your lectures!!! you guys do an amazing job!!!
i just want to solicitate one thing: could you put the references of the lectures in the description? this would contribute to a guided study of the subjects
U r a savior for me ... thank you so much sir 🙏
I just want to make a point of clarification. Dysphonia should be a weakness of the soft palate not the larynx because phonation or guttural sounds are made by the elevation of the soft palate to obstruct the nasopharyngeal passage. But I'm just being too technical.
All in all, i love these lectures and it makes understanding all the long neuroanatomy books so much easier. It is so hard to read books like Carpenter's which is so deep or books by Snell which is so superficial without getting lost or loosing concentration. I wish my teachers in anatomy could teach like you. All praises sir and more power to your advocacy of teaching future doctors. Full respect for your knowledge and your love of teaching.
Dysphonia can also arise from vocal fold palsy or paralysis following lateral medullary infarction
I love your work and all your effort! Thanks from a Italian Medical Student
Thanks a lot sir..I had much difficulty to understand it and now I have understood much
You are great Zack, thank you
incredible!! you just made neuropathology way easier thanks!!
You are simply amazing 🤩🤩🤩
U make subject fun to learn 👍
Superb sir👍👍
Awesome incredible explanation thanks a lot
Carry on zach please make videos of neurophysiology
please cover upper and lower motor neuron lesion
Please make a video on Internal capsule and internal structure of cerebral cortex (neural Tracts)
I would give you 10 years of my life and that still wouldn’t be enough to thank you
Awesome content! Many thanks!
Indeed you are a superstar and a genius teacher with a very pleasant personality . I have learned a lot from your videos. Yet allow me to ask you a few questions 1) In the trigeminal ganglion loss of the medullary part why do we lose the sensation on the ipsilateral side of the face while the other nuclei of this same nerve that are present in the pons and midbrain are still intact. 2) What is Wellenberg syndrome . 3) A personal question ... why do you always put a hat on your head? Many many thanks from Lebanon.
You are the best Neuro teacher
You are amazing Zach
awesome as usual
Thank you for teaching us! If you could please make these videos a little longer because they are awesome; jk, whatever length you make them it’s awesome. Thank you Ninja Nerds.

Amazing!
Great description.
Woow just woow...u are the master
The Legend !
Do cuneate nucleus and gracile nucleus not get involved in lateral medullary syndrome?
I was going through Harrison's Principles of internal medicine, where I found so.
Dunder Mifflin😄
I really appreciate your efforts!
Yeah Mr Zach yeah science ⚡⚡
THANK YOU SIR!!
no one has disliked this, that's what I like to see
رائع جداً جزاك الله خيراً
Great videos, thank you! could you maybe make some more concise videos for quick reviews (10-15min) if you haven’t already?
I have chiari with lateral medullary compression . Vestibular nuclei and pharyngeal plexus prominant. 10/2020 surgical crainectomy and laminectomy. Still suffer many symptoms. Some new ones also. I have a few questions since your more educated on this topic than any of my doctors. Would you be open to that?
Superb Sir.
Freaking amazing.
My husband you're back and looking BETTER THEN EVER!
it is so painful that you are not getting views
Thank you ❤
Never let's us down!!!
Why I/L loss of Pain, touch, temp in lateral medullary syndrome?
The fibers of spinothalamic tract decussate in spinal cord only should it not be Contralateral??
Great, superb
🙏🙏🙏🙏🙏🙏🙏
THANK YOU SO MUCH.......
Damn good.💯❤️ Thank you
love uuuuu zaaach😭
