ANATOMY CARDIOVASCULAR SYSTEM TEST REVIEW LeGrotte 2014 1. Which wall of the heart is thickest and why? The myocardium (cardiac muscle)‚ is the thickest section of the heart wall and contains cardiomyocytes‚ the contractile cell of the heart. 2. What part of the heart is the pacemaker and why? The SA Node is located in the right atrium of the heart. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the

Chaper 11 1. Define responsiveness‚ conductivity‚ contractility‚ extensibility‚ and elasticity. State why each of these properties is necessary for muscle function. a. Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces

BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists
