I'm learning a lot through your videos especially now during quarantine and our professors will be giving us exams despite not sending any lectures. Massive thanks for all your videos. It's a great help to a lot of struggling med students like me.
I cannot thank or commend you enough for putting together these types of videos. They are so easy to follow and your explanations are so clear. Thank you for helping me learn such interesting content!
Your videos are so good, informative, and narrated at a great pace. Aided with your simplistic but detailed drawings, make for a really useful and educational video. Watched a few on various topics that have never failed to help. Thanks for making the videos and the help.
Thank you for making this video. I had such a problem grasping these concepts and you explained it perfectly and made it clear for me to comprehend. You have a gift for breaking things down. My professor goes through the topics so fast and the text is difficult to understand. I am truly grateful. Thank u again. I’ll be checking out your other videos. ❤️
At 7:22 the narrator says that "all synaptic reflexes involve interneurons". This is almost always the case, but not in the case of the stretch reflex which is a monosynaptic sensory --> motor synapse.
Steph Paoli I can’t understand something .. how stretch reflex is monosynapse when it has afferent that synapse with other efferent that inhibit the antagonist muscle ?
@@dinasayed9946just because they aren’t really “inhibiting” the antagonist, the antagonists should not be flexed for a reflex test. when you’re at the doctor, you knee is just free hanging off the edge of a chair/seat, you are not contracting any muscles to do so. when you hit the patellar tendon, you are only activating the quads to extend your knee
The information on the upper motor neurons being excitatory or inhibitory makes so much sense as to why you get hyperreflexia and + Babinski sign. Thank you!
This is a great video, I was stuck on the exact mechanism of the myotatic reflex and how the gamma motor neurons and alpha motor neurons were stimulated. This video made it as clear as day, truly remarkable how it can be made so simple yet my med school professors make it seem so complex smh. Thank you!
Think about this: If you were to remove your ability to hear, then your sight, and then your ability to feel and then smell, what would your conscious experience be? Now imagine you were born that way (without any senses)... So now you have no senses and no idea of anything= no referential experience what so ever. What would that experience be? Our experience is dependent on our senses, and our faculties for sensing is all automatic= Reflexive. Reflexes are all electrical. Now extend this fact to every cell in your body: Billions of cells simultaneously reflex to give rise to the sensation of self and "consciousness".
The brain cells are just as reflexive to external stimuli as the parts of the body you've pointed out in this video. It is a chain reaction that has started before our birth and started with the very first organism.
Thank you, I think we can shall may ( or any suitable helping verb ) all understand about the impulse energy fear repetitive thoughts can generate and use it for good reason like laughing, understanding the logic so that fear reduces, time and speed at which it attacks, etc., at accurate time so that we can shall may ( or any suitable helping verb ) waste energy on fear, actions from fear, breathlessness, degrading ourselves , addictions, panic attacks, hurting ourself and suicide etc
Around 13:30 - I still don't understand why the toes extend upwards - Yes, I get that due to pyramidal lesion / underdeveloped pyramidal system there will be no inhibitory message from the upper motor neuron, however, in the video it doesn't mention any excitatory message that is being transmitted to the extensor muscles of the feet / toes, so, why do they curl up? on top of that, we still have an excitatory message to the flexor muscles of the feet, so I don't understand how the babinski sign happens. I guess the actual response is much more complicated than the one given in the video? Anyway, great video regardless.
🎥 DON'T JUST WATCH, LEARN ACTIVELY! TRY THE QUIZ! 🤓

I'm in med school too. All the best! 🍀
Am in the same situation from JKUAT Kenya...all the best fellow medics😎
Same ..med student from South Africa here
So r u a doc now?
You're actually so good at drawing it's scary
I have never hear such a wonderful explanation. Really enjoyed while watching it....

Thanks!
Best ....... artist + teacher
This video was beyond helpful! I loved the illustrations being drawn at the same time as the explanations. The drawings are actually really good.
you explained all my reflex lectures in 15 mins. thanks a lot armando. i am learning a lot from you than my lecturers lol

Same here. It's actually kind of wild to experience how some instructors really don't have the skills to deliver information in cohesive ways.
You make complex things really easy❤️
You just helped me so much a day before my exam. Thankyou so much ❤️❤️
I really admire your sketching

Because they are bad teachers. I have the same problem. Have to learn most of the things by my self, lectures are unfortunately subpar. Good luck !

You’re 10x better than my professor
Conflict ..clear because of you..😊
Thank you for making it so easy to understand!!!

Dude this is the best.Thank u
Thanku so muchhhhh...plz do more videos on first year MBBS physiology.....xams are nearing
Does anyone else hear what sounds like birds chirping in the background, or am I losing it?
Please make a video on length servo and follow up servo mechanisms.
Very good
This is what I study as a second-year secondary school student in Algeria
At 12:20, isn't the plantar flexion reflex a polysynaptic reflex.
Neural circuits are hard for me to remember, especially once you get to different sections of the CNS

Thanks a lot! Keep making videos, please
