Symptom Relief. Sips of milk help sooth symptoms of heartburn and ulcers caused by excess stomach acid production. Unfortunately, drinking too much milk causes your stomach to increase its acid production and eventually worsen your symptoms, warns Gloria Tsang, a registered dietitian for HealthCastle.com.
Pacemaker cells and Purkinje fibres in the conduction system are specialized cardiomyocytes that generate and conduct electrical impulses. The sinoatrial node (SAN), which is composed of a group of pacemaker cells, resides in the right atrium generating impulses to initiate heart contraction. The atrioventricular node (AVN) is located between the atria and ventricles, and it conducts an electrical impulse from the atria to the ventricles. Mei Xin,
The electrical conduction system of the heart transmits signals generated usually by the sinoatrial node to cause contraction of the heart muscle. The pacemaking signal generated in the sinoatrial node travels through the right atrium to the atrioventricular node, along the Bundle of His and through bundle branches to cause contraction of the heart muscle.
