[ajulia91]

this video is amazing ! i cant learn reading my txtbook and this really helped because its visual!!! thanks heaps :)

[moos209]

you're jordinian?

[hyperhighs]

@moos209

Afghan :)

[MrUtriculo]

Thank god I have a book ,nothing new to learn of this video

[hyperhighs]

@MrUtriculo Hahaha, yeah, thank god you got a book... that's what i keep telling people - my videos are a review

[57607]

Wow you are talented! very beautiful drawings I shall say

[Nojoud91]

Thank you for taking time to make such a useful videos

but would you mind extracting the musical sounds

because they're distracting, I want to understand and concentrate.

Thank you very much.

[nh1zgrip71]

This helped me immensely. I asked about the pressure difference is my graduate physiology class and my professor mentioned nothing about the stretching of the atrial septum, the attachment to the diaphragm or the negative pressure...omg...thank you so much for this understanding. I can't wait to share this with my classmates!

[shosho8224]

awesomeeeeeeeeee ...thank you doctor ..:)

[tarlacnepali]

hi sir....i went through ur tutorial and read the book too.. it is really helping me....i m confused with one thing...when explained in the lecture that the atrial contraction causes 10% filling of ventricular blood but the book that i m reading says it is about 20 % ..which one should i follow.....and why is there a difference...thank for uploading the video u been a great help...

[tarlacnepali]

There is a rare disease called cardiocephalo hypertrophy...these kind of people are special and one of them is u Mr. hyperhigh.

[Sederich]

it is not true that the apex of the heart is not able to move...it is not even fixed somewhere but swimms freely in a fluid within the pericardium...nice videos though

[juulmon]

@Sederich actually the apex is indirectly fixed to the centrum tendineum of the diaphragm through the fibrous pericardium, (also fixed to a bit of the diaphragm muscle on the left side). Since the fibrous pericardium loses itself in the outer layers (tunica adventitia) of the aorta and superior vena cava you can look at it like a vertical fixation to the diaphragm

Reko ti moj cimer Germa da nabije na kurac i tebe i taj tvoj neki ligament

[puri180]

thx bro, i got it

[PrimeParadox]

you are amazing.

I bet ur a straight A student.

[webstudy]

thank you=)

[webstudy]

giving my fourth and final final prof in two months..it all comes down to the basics doesn't it?? THANK YOU=)

[divaexpatriate]

Is that Rohen's? I love that book

[bullet4some1]

the atrial contraction contributes 20 %--- according to Guyton

[Tunedup81]

lmao, I feel like i've been lied to!! To make it short, I had open heart surgery at 19 to fix a "Possible" hole in my heart from birth, recently I was diagnosed with Atrial Fibulation right.. well I asked the same cardiologist if it was caused due to the open heart.. he said not likely... that I was probably born with it.. Your explaination makes it sound like my SAME symptoms could be caused by Atrial Fibulation, because after that surgery My symptoms had NO change what so ever.

[Tunedup81]

does this make sense? My cardiologist KNEW what was going on, but missed it and assumed it was a hole causing my problems.. absolutly no change post op. was made to my ability to exercise without feeling faint, out of breath etc etc. .. hrmm.. i feel kinda violated..

[afrosaxon1]

thankyou soooo much, such a good vid!!

[ZainabHamed]

ur amazing mashallah...God bless you!!

[ceriberrycherry]

excellent, thank you so much. much clearer than my anatomy teacher!

[llggrrgg]

you have helped me a lot, usually the physiology books arent that explanatory. Thank you very much!

[jacksjoes]

wow,awesome explaination!thnx a lot..

[onebleach3]

dude, u truly are an amazing teacher.

[navuchodonossor]

hyperhighs , Heart Ligament?? wha kind of ligament is this?

How can there be a ligament that attaches the apex to the diaphragm since the heart is surounded by the pericardium.

It's existence explains nicely the atrial filling but is there really any ligament there?

[hyperhighs]

Yes there is - according to my MD professor - but it is not in my anatomy book.

[navuchodonossor]

Appreciate the quick response but I have to admit there... not very enlightening! I am too having a hard time to find that ligament in my books or remember it from the lectures. Haven't asked yet our professor of CT surgery though. Long story short, :) it would be very helpful if you got any "intel" on the ligament after all

[ceriberrycherry]

According to an antomy book on internet, the central tendon of the diaphragm attaches to the base of the heart at the fibrous pericardium (which surrounds the heart.)

Just checked in Gray's, that's right.

[chandalsaitan]

@hyperhighs well the apex of the heart generally denotes the lowest portion of the heart but if we need to put it theoretically it is the pericardium that is connected by the sternopericardiac ligament to the diaphragm..the fibrous pericardium is attached to the posterior surface of the sternum by the superior and inferior sternopericardiac ligaments..upper to the manubrium and the lower one to the xiphoid process.

[Pe2805M]

well, according to what I found, there is phrenicopericardial ligament in small animals or mammals like dogs or cats...

[BF1]

@navuchodonossor Yes Netter's anatomy shows the pericardium attached to the diaphragm. He does not label it anything specific but just calls it "line of fusion of fibrous pericardium to diaphgragm"

[ghalan100]

very good tutor. I am catching you and waiting you for all the lectures in medical course . By the way i am a medical student . i need your documents. and i ma feeling your explanation very admirable.

[athaker]

Nice explanations! You have anything on the Guyton Curves?

The dramatic music, by the way, excellent effect. Brings true gravitas to your presentation!

[gaidee]

thx a lot for ur vid, it was a good revision for me ;)

[Haneiyuu]

nice, job, I suck at heart physiology and this is making it really clear. thanks.

[edisonschest]

Teacher's like this guy are hard to find. Wish this teaching tool was available when I was in school? Nice review.

[ekwlee]

god..you are awesome..if u ever need someone to tour you around in hawaii let me know!! i owe you ALOT!!

[DoctorKia]

[abuzerkom]

Very helpful, thank you for your post. I want to make a point. I believe that 70 percent of ventricle filling is passive and the rest is active (but we both agree on that the most filling occurs passively).

[nozimom]

Thank you! Thank you! Thank you! You are truly gifted, and I appreciate that you are willing to share this gift with all of us searching for understanding of complicated information :)

[ameliabedelia99]

hey, i studied human biology and nursing at u of t!

anyway, just wanted to say thanks - you really know your stuff and it's a great refresher.

[jsmith5052]

u should do some stuff on the human hand

[24854415]

Im an EMT taking my paramedic course at the moment,this is very helpfull,Thank you

[200502122]

thx for all the lectures but i would be greatful if you could possibly make an video of respiratory and endocrine physiology.

[spogi]

another brilliant set of videos from u! Very well made and your drawings are like netter sketches. Thanks for the videos. Keep it up!

[Dokgoth]

omg, this reminds me of med school, good work

[promiscuousgrlbel]

Thank you so much for the video. I need to know this sort of stuff for pharmacology and it really helped.. you're very smart thank you!!!

[tocheroro]

pls where are you from? i want to be having tutorial with you online i am a medical student how can dat be possible? thanks for you reply pls send any chat list you have

[hyperhighs]

Hi.. unfortunately there is a misunderstanding. I am not a medical student, i am a physiology spec. student. Which is why as you can see i post mainly anatomy and physiology videos and nothing on "clinical" stuff. However, i will suggest that you visit "o2demand".. he has all the clinical physiology. You can find a link to him under my favorites, unless you already know about it. Bye.

[tocheroro]

Hyperhighs do you have any for other topics like digestive system and so on? please tell me where to find it

[hyperhighs]

Hi... sorry, i don't have those topics.. i haven't had a chance to make them. I also am not sure where you could find those topics except in physiology books. Sorry again.

[o2demand]

hey tocheroro, i have some topics such as neuro, cardiac, respiratory, renal and hepatic physiology if your interested. Also creating pharmacology as well!

hope it helps...hyperhighs is gifted and always enjoy viewing his videos

Hyperhighs,thanks so much for all your video's! Very helpful for visual learners like myself.

[unison00]

thanks!!

Spacibo

[partymarty111]

why is the right side of the heart on the left and vice versa. its quite confusing

[hyperhighs]

Imagine taking your heart in your hand and looking at it's anterior surface. What do you see?

[partymarty111]

oh yeah. doh!! thanks for that

[omaha987]

because it is on the right side of your perspective....the right side of your heart will be the left side when we watch it......just like your left hand is on the right side when i watch u....no dont feel stupid

[sweetinnocenty]

Nice work dear.thanks for sharing it.

God bless you.....

[wukjoy]

Thank you for this video. This is a great help for students like me. :)

[calvleo1]

Nicely done... Thank you for making the video.

[EdisunJay]

Thanks for the explanation. :D

Your videos are greatly appreciated.
