Frog Heart Dynamics as a response to different Drugs

A simple over view of what occurs when drugs like epinephrine, ACh, Atropine are administered to a frog's heart. Also what occurs during certain ion imbalance as represented by calcium chloride and potassium chloride injections.

very neat and creative way of demonstrating the effects of drugs on the frog heart well done

At 0.35min....What the top graph about...What is on the x-axis and y-axis?

@BF1 Did I miss the point or did you? I don't think I can't even reach near a sense of feeling from you... you are to cerebral and far, far from the essence of light, love, compassion, respect. I'll rather be naive than having more knowledge a the cost of someone else suffering or life.

@letstradeusa Obviously you missed the point. The idea is to show the physiology of the 2 chemicals that adress heart physiology of the sympathetic nervous system and parasympathetics (NE, and ACh) and the ones that affect the channels Ca++ and K+. It's one thing to know them in theory but its another to see it visually live.

That frog died of a broken heart.

Thank you, I'm here all week. Try the veal.

I thought that the frog is not properly pithed as it moved its arm at 2:46.

@eugenedaman No the frog is not alive. I teach physiology and it is a standard lab experiment for the class. But if it were, it's still a very neat lab experiment.

Great video... Thank you guys

@paleopod1226 Indeed.

Also, just to clarify, the frog is NOT alive during this. The heart beat is "intrinsic" meaning that it is caused from within the heart. It will continue to beat for hours even if it were removed.

[letstradeusa]

would do that to a human? If not why is this ok to you?

Did the frog arm just move? That was freaky!
