Human Heart. need help!

[Tito L. Oracion]

@Tito

There are a groups of cyclically connected nerve cells
called neurons in the heart muscles themselves that
cause the heart to beat. The heart beat is propagated
like a wave through heart tissue due to the lack of instantaneous
signalling. It is very much like a bistable multivibrator in
electrical circuits. As in all things biological, it has redundant
parts and chemical intermediate messangers (proteins) serve
to communicate information from other organs that bias
the environment of these neurons so as to provide open
loop control. These things are evolutionarily neat but the
sum total makes biological systems some of the most complex
systems dealt with by the human mind.

One thing that can happen is that a chaotic overspeed
process can develop that cause the heart muscle to
continuously quiver rather than beat. This is when
medical personnel need to apply cardiac defibrillation, a
high voltage capacitive discharge to heart, to terminate
the chaotic processes so the regular beating process can
regain control of it.

How these biological systems that uses 10's of millivolts as
nerve data transfer mechanism can possibly survive something
like a lightning strike is totally amazing and well beyond current
electronics technology used in computers ect.

Thank you sir!

See,
I don't remember saying that?

Maybe I did ?

I'm still learning how to speak "yellow face".

No! my question was, what is the one that makes the heart muscle moves or pump or pulse, is it what?

Most voluntary systems operate oppositely the involuntary systems, it's unusual this way.

The same signaling in one are of the nervous tissue may turn something on, while in yet another it turns something off.

I think that stimulation of the nerves going to the heart causes it to slow down, while stimulation of those same types of nerves elsewhere would cause something to activate.

Whats with all this heart stuff?

Are you like Dr. Frankenteets now?   

Whatcha building?
