Slow initial depolarization caused by closing of K+ channels. Next funny channels open. Allow Na+ to enter causing depolarization. Only open briefly. This depolarization opens two types of Ca++ channels

: provide the conduction system that allows the heart to beat. Electrical impulses move down axon via potassium/sodium channels, dendrites communicate to next nerve cell body via released chemicals that connect to receptors in the cell body. Fat cells: protective function, possibly insulation. Always around arteries and veins. Sheep or Pig Heart:

E. Cardiac Conduction System . 1. Specialized cardiac muscle tissue conducts impulses throughout the myocardium and comprises the cardiac conduction system. 2. A self-exciting mass of specialized cardiac muscle called the sinoatrial node (S-A node or pacemaker), located on the posterior right atrium, and generates the impulses for the heartbeat. 3.
