Cardiac Physiology The heart: chambers, the valves Cardiac muscle cells Some cardiac muscle cells are autorhythmic Arrangement of cardiac muscle cells Excitation-contraction coupling Atrioventricular (AV) Valves guard the passageway between the atria and the ventricles Tricuspid valve between right atrium a...
Clinical studies have identified striking differences between men and women in the incidence and expression of many different cardiovascular diseases. This should not be surprising; there are also sex differences in the normal structure and physiology of the heart. Although information is limited, there...

Muscle Contraction – Step 3 The axon branches to supply a number of muscle fibers called a motor unit, and the action potential is conveyed to a motor end plate on each muscle fiber. Muscle Contraction – Step 4 At the motor end plate, the action potential causes the release of packets ...
Muscle Contraction. We have 400+ muscles in the body which comprise 40-50% of the total body weight There are three types of muscle: Smooth Cardiac. Muscle Contraction

Auscultation of heart sounds is an important veterinary skill requiring an understanding of anatomy, physiology, pathophysiology and pattern recognition. This cross-sectional study was developed to evaluate a targeted, audio-visual training resource for veterinary students to improve their understanding and ...
