Myo means muscle. While I'm on the myocardium, let me just point out one more thing.

Well, an orgasm is simply a series of muscle contractions.

Guys, systolic's in freefall.

You squeeze your hand, these muscles contract.

It takes about 40 minutes to print, and about four to six hours later you see the muscle cells contract.

And that's basically what's called a power amplification system.

What happens after this? The ventricles are full of blood and let's say they squeeze.

Contraction

And it sounds like an easy problem.

So the muscle contracts, and nothing happens.

If the parasite is constricting, this might loosen its grip.

You'll hear S1 again over here and S2.

I would have to bend my elbow, and then I would have to cocontract to get it to change modes.

I had to use my bicep to get the hand to close, use my tricep to get it to open, cocontract again to get the elbow to work again.

And that person will be sad.

But apart from that, everything else goes through contractions of muscles.

Gravity wins over all other known forces.

The ventricles are very strong, right? We know the ventricles are really really strong.

So when I stand in these legs, my hamstring and my glutes are contracted, as they would be had I had feet and were standing on the ball of my feet.

Your muscles atrophied. We're rebuilding them.

What I mean by that is, let me show you what happens a moment later.

These are particularly important for when you're trying to make sure that ventricles don't screw up the valves.

This would basically start flipping back and forth, it would flip this way and this way.

Mind over matter.

Mind over matter.

Mind over matter?

In muscle, they corkscrew, so that muscles can contract without cutting off circulation.

Every time you contract a muscle, it emits a little electricity that you can record with antennae or electrodes and use that to operate the motorized prosthesis.

Here's an example from Kevin Eggan's lab at Harvard.

Let's consider here the case of Dilated Cardiomyopathy.

You can actually now in diastole move some blood forward because the elastic energy is recoiling like a rubber band, and that energy has to go somewhere.

This is actually a light emitter.

Some part infarct, that's what they called myocardial infarction. Myocardial means the tissue of heart or the muscle of the heart that's dying.

Now on the other side of the myocardium, what do we have on the outside?

Now you can listen to your heart and figure out, well if you listen to the sound between lub and dub, the space in time between lub and dub, that's when you're having systole.

The elbow exam begins with inspection.

Her orbit is rapidly decaying.

It's a cardiac stress test.

And what he showed in mantis shrimp is that they use what's called a catch mechanism, or click mechanism.

If it cannot cool faster than collapses, then it'll be just pure gravitational collapse on a free fall time scale.

Is it possible that muscle somehow intuitively knows that it needs this blood supply?

The heart is made of muscle.

Select the center point of the scaling...

'Company.'

Now, in a typical stress response, your heart rate goes up, and your blood vessels constrict like this.
