4. In most cases, the heart muscle weakens and is unable to pump blood to the rest of the body as well as it should. Usage Frequency: 1 Depolarization is essential to the function of many cells, communication between cells, and the overall physiology of an organism. In slow response, the action potential gets conducted more slowly than the fast response. What does myocarditis mean? Cardiac muscle. Reference: Anonymous, Last Update: 2016-10-20 Quality: Increase in ionic calcium increases the force of contraction. iii. Once the cardiac muscle is depolarized, calcium ions (Ca++) enter into the ICF. 4. What does cardiac muscle mean? Usage Frequency: 2 In this phase, in spite of semi­lunar valves being in the open state and the pressure being more in the aorta than in left ventricle, there will not be back flow of blood into the ventricle from the aorta). These factors either dilate or constrict the vessels to adjust the flow according to the needs of the concerned part of body. Telugu words for muscle include బలము, మనిషి శరీరంలో ఉండే కండరాలు and కండర. Meaning of cardiac muscle cell. Blood is about 5-6 times more viscous to that of water. Reference: Anonymous, Last Update: 2016-06-27 It states that the force of contraction is directly proportionate to the initial length of the muscle fiber within physiological limits. 3.3). The word arrest means to stop or bring to a halt.In cardiac arrest, the heart ceases to beat. Know more about Syphilis, its causes, symptoms, treatment and other useful facts, links and videos on Health-Wiki | Practo It exchanges three sodium ions for one calcium ion transported out by an ATP-driven calcium pump. And the innermost layer is made up of endothelial cell, the tunica intima. While similar to skeletal muscle, cardiac muscle is different in a few ways. This prevents the heart ventricles from expanding fully. These dangerous lesions are the forerunner of a disease known as atherosclerosis. Privacy Policy3.

Reference: Anonymous, Last Update: 2016-03-19 In most cases, the heart muscle weakens and is unable to pump blood to the rest of the body as well as it should. Therefore, there will be calcium influx. Reference: All_inclusive_Christ, Last Update: 2015-05-10 This is known as resting membrane potential. A heart lesion is any stress or trauma delivered to the interior walls of the heart, resulting in tissue damage. Quality: i. The conduction is more likely to get blocked compared to fast response. When severe, it can result in coronary artery disease, stroke, peripheral artery disease, or kidney problems, depending on which arteries are affected. We use cookies to enhance your experience. The “L” channels refer to the long-lasting calcium channels. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes.
