The Conducting System. Introduction The heart's conducting system consists of the . sinoatrial node (SA node), atrioventicular node (AV node), the bundle of His, the bundle branches and the Purkinje fibers. The electrical impulse that causes rhythmic contraction of heart muscles arises in the . SA node. which is the intrinsic pacemaker of the heart.

4. Cardiac veins drain blood from the heart muscle and carry it to the coronary sinus, which empties into the right atrium. The Heartbeat. Two types of cardiac muscle cells are involved in a normal heartbeat: Contractile cells. Specialized muscle cells of the conducting system, which control and coordinate the activities of the contractile cells.

The conducting system of the frog heart is essentially similar to that of the human, except that the pacemaker of the frog is located in the wall of the sinus venosus. NOTE: The entire central nervous system of the frogs used in this experiment has been destroyed by pithing. As a result they cannot feel pain or respond to stimuli.

20-2 The Conducting System. Prepotential. Also called pacemaker potential. Resting potential of conducting cells. Gradually depolarizes toward threshold. SA node depolarizes first, establishing heart rate. 20-2 The Conducting System. Heart Rate. SA node generates 80–100 action potentials per minute. Parasympathetic stimulation slows heart ...

Conducting system of the heart. SA node AV node (bundle of His) bundle branches (right and left) Purkinje fibers. Innervation of heart. Ach in parasympathetic which decreases heart rate and contractivity of myocardium. Muscarinic receptor for Ach in parasympathetic decreases heart rate, contractivity of myocardium, and conduction velocity.
