Mam u teach so well, u r the teacher i always wanted! Never understood the basis of differentiation of waves, but this video made that digestible. JAZAKALLAH
Aap itna acha padhatey ho chahe number aaye na pr mujhe aap se padh kr samjh aa jata hai dil sukoon milta hai aapsey padhkr ❤ Thank u so much mam thank u so much ❤
Even for my neet pgexam just watching ur video is so understandble💓 mam Crisp ,concised with clear cut explanation Really miss😢ing Never found this channel earlier 😕
ma'am , though totally unrelated to the topic , I have confusion regarding venous pressure . You are the teacher I reach out for when anything confuses me and you never disappoint . In Guyton and hall textbook medical physiology , It is stated that the blood pressure in neck veins is 0 mm hg probably relative to atmospheric pressure and -ve pressure on dural sinuses , then why isn't the venous blood sucked up instead of reaching down to right atrium . And it is also stated because of this during brain surgery when cranium is opened there is chance of atmospheric air getting sucked in leading to embolism . I am not getting a single thing about this .
Sorry for late reply...but I searched , searched and searched. Nowhere it is mentioned that they have negative pressure Only I think during neurosurgery the pressure can become negative when the hard walks are suddenly opened , that too in certain positions Is it speciafically written in Guyton that they always have negative pressure?
blood flows from areas where TOTAL PRESSURE (TP) is high to areas with low TOTAL PRESSURE (TP). the blood pressure readings are not the total pressure they are just a part of it which is given by Bernoulli's equation. TP = F/A + pgh + 1/2pv^2 . the blood pressure readings is the F/A component, and we should also consider the pgh component where p=density, g=acceleration due to gravity and h = height, as the blood in the neck is higher than right atrium, this pgh component is bigger and more positive for the neck and so the total pressure is actually greater in the neck than the right atrium. Again the blood pressure readings are just part of the total pressure not all. another example is that blood pressure is greater in the feet than in the aorta but blood still flows from the aorta of the arteries in the feet this is because again total pressure is higher at the aorta than the feet as the aorta (due to the larger pgh component). anyways i recommend watching videos on Bernoulli's equation as its not a straightforward concept.
How can we explain the paradoxical sleep ? Can we say that the high activity of the brain in this stage is because of dreams (since in this phase we start dreaming )
Or is it because of the high activity that we dream...can’t pin point that...but yes neural activity is similar to awake state..many things are not known
@@PhysiologyOpen Another question please , can we say simply that synchronized waves like delta waves indicate low activity of the brain , while disynchronized waves indicate high activity of the brain ?
Better to say...synchronised is sleep and desynchronised is awake like...by the way it’s sensations and their inputs to thalamus which cause synchronisation/desynchronisation (known as thalamostriatal projections) For initiation of sleep, we want less sensations- like switching of lights, minimum sound, comfy bed..decreases projections to thalamus ..and then synchronisation of waves
Excellent video thanks for posting
Pleasure is all mine

Thank you! It's so rewarding to hear that my videos make complex concepts clear.

Tumne ek dam mere dil ki baat keh di…3 idiots ka ek dialogue yaad aa gaya…excellence ke peeche jao, kaamyabi apne aap aayegi…number bhi aayenge
Well explained Maam🔥.
Go through ur most of the lectures and it was like "In search of Gold i got Diamond". Thank you so much maam for ur hard work.
Thanks a ton. Really happy
True, in depth study.
YOU ARE THE BEST TEACHER EVER! thank you very much for this clear, detailed and logical explanation .
I try …😊
Another excellent video that I watched . You are really helping me gain fundas for my neetpg prep. Thank you so much mam 🥰
Thank you …for motivation..happy that what I am trying is reaching you
You are too good to explain the topics Mam
I try
Even for my neet pgexam just watching ur video is so understandble💓 mam
Crisp ,concised with clear cut explanation
Really miss😢ing
Never found this channel earlier 😕
Thank you so much 😊❤️❤️
Awesome maam…
U explained in a very simple nd understanding way..
Glad to hear that
best video on eeg and sleep out there ! thank you
Really glad. . Thank you so much 😊
Good retention with visual & aural input of VARK learning.
😎
Mam your teaching style is too good, please make videos regularly 🥺🙌
Yeah now starting to videos again
Was busy preparing physiology notes
@@PhysiologyOpen Thanks mam ✨
Well explained... 👍🏻👍🏻
Thank you 🙂
best teacher of physiology
Humbled. Thanks 😊❤️
Omg ma'am! 😭🙌 Thank you so much for explaining so well ma'am! ❤️❤️❤️
Thanks and welcome 😊
Thank you! Straight and simple explanation :)
Thanks…glad you liked it 😊
Best explanation ma'am...
Thanks 😊
Great explanations
Thanks
Really amazing,😍
Thanks. Happy that you liked it
Thank you Ma'am🌟🌟🌟
You are welcome
Thankyou mam🙂
Keep watching
Hello mam. Pls do video on ear . Mechanism of sound transduction and agnosia. Aphasia s and cerebral cortex layering. And more of CNS topics mam.
Coming up one on sleep physiology tomorrow. Will do others soon
Tyyy❤
Most welcome

Thank you so much for the video ma'am. Can you please explain the applications of Laplace law in Physiology.
Thank you for the suggestion . Will love to work on that video. I will really appreciate if I come to know more topics like that
@@PhysiologyOpen Thank you Ma'am.

Mam pls do a vedio on cerebral autoregulation.!!!!
Will do next
Where are you from madam?
From UP mostly…then from many other places in India
Excellent Sir
Thanks. But it’s madam
Thank u mam, ❤️
Pleasure is all mine
Excellent
Glad you liked it
☺️❤️
❤️🙏
🎉.
😊❤️
Omen service.......
🙏
