Cardiac Accelerator Nerves

In this video, I will explain cardiac accelerator nerves, which contain sympathetic axons, supply which sections of the heart, and when action potential conducts through the branches of cardiac accelerator nerves, how the heart rate and stroke volume change as a result. At the end, I will review the neurotransmitter molecule released from cardiac accelerator nerves and the receptors in the sarcolemma of the cardiac muscles for this neurotransmitter molecule.
