Electrical properties.(Anatomy and human physiology )?

hi everybody =)
i'll be having my presentation by subsequent week..i really need to know how to deliver hypothesis on;
1. electrical properties of cardiac muscle cells
2. electrical conducting system of the heart
thankfulness so much on your careness..i dont have design about this topic..hope somebody can share sth near me..thanks again!! cheeerio (",) Dude read up. You do enjoy a text book dont you? It's in attendance with adjectives the cool pictures. I mean you enjoy a presentation, and you dont' wanna read up? You want us to do your hw?

Please see the webpages for more details on Electrical conduction system of the heart.
If you have taken an anatomy course later you already know.
seriously man, it probably took longer for you to ask this on yahoo than it would have to look it up on google. here is a air, look up pacemaker cells.
Heart muscle is a immensely specific muscle. When it's excited, it responds to the rule of "All or nothing at all" within other words, when the heart muscle is excited, a wave moves over the heart muscle cause it to contract. Once the wave moves over (top to bottom) later the heart muscle relaxes from bottom to top.
The electrical trigger is in the SA node, an identifiable spot surrounded by the septum wall, that is glibly excited and, once excited, the heart contracts.
