This is called the funny current (also known as pacemaker current); it is active at TMPs of less than −55 mV. Separate pages describe the types and structures of arteries, characteristics of blood flow, and information on lipoproteins . However, the effect may be beneficial in the context of decompensated heart failure, where the decreased preload and afterload result in a return to a more productive part of the Starling curve. This is a great way to determine how many slides you want on a page. The normal pattern of excitation begins with the spontaneous appearance of action potentials in the Sinoatrial node (SAN) , which spontaneously generates action potentials at a frequency of 60-100 per Cardiac muscle tissue is only found in the heart. 3. 8 inches tall and 3. – Increases amount of blood returning to heart and causes heart to contract more forcefully (Starling’s law) • Helps to maintain or increase cardiac output 47 Nervous System Control of Heart • Autonomic nervous system also controls behavior of heart – Influences heart rate, conductivity, and contractility "Chapter 1. as.

Cardiovascular physiology is the study of the circulatory system, specifically addressing the physiology of the heart and blood vessels. As in skeletal muscle, cardiac myocytes contract according to the sliding filament theory of muscle contraction. Whereas the action potential for skeletal muscle and nerves is due to the abrupt opening of voltage-gated sodium channels in the cell membrane, in cardiac muscle it is initiated by voltage-gated sodium channels (the spike) and maintained by voltage-gated An important aspect of properly performing ACLS is having a strong understanding of normal cardiac anatomy and physiology.
