The cardiac muscle is supplied by nerves, but the nervous system merely helps regulate the speed and strength of its contractions. Unlike other muscles, cardiac muscle is nearly completely reliant on oxygen to function. While skeletal muscles can function anaerobically, using stored glycogen as a ...
Which is NOT a correct comparison of cardiac myocytes to other muscle cell types? A. Like smooth muscle cells, some cardiac myocytes have pacemaker potentials. B. Like some smooth muscle cells, cardiac myocytes are electrically coupled. C. Like skeleta ...
What muscle or part of the muscle is an antagonist in its action to the Rectus femoris? What does human muscle contraction have in common with cellular movement in single-cell organisms? What are involuntary muscle contractions that move a bolus through the gastrointestinal tract called? What mus...
@boathugger: It’s called action potential. The contractions of the cardiac muscle are triggered in a different way than the contraction of the skeletal muscle, which is caused by electrical impulses from nerve terminals located at the individual muscle fibers. ...

For instance, when adrenaline binds to smooth and cardiac muscle cells, it causes them to contract, which: Keeps most of your blood circulating to your heart, lungs, central nervous system, and the large muscles in your arms and legs
What Is a Muscle Cell? What is the Cardiac Muscle? Discussion Comments ByTalentryto— On Feb 04, 2014 Not only is the masseter, or jaw, muscle one of the strongest muscles in the human body, it can also cause a lot of pain. TMJ, teeth clenching, and teeth grinding all can lead to...
Your body is made up of three types of muscle: cardiac, smooth and skeletal, according toThe Library of Congress. Cardiac and smooth muscles help protect the internal organs of your body. While cardiac muscle protects the heart and keeps it pumping, smooth muscle makes up the walls of your...
heart program which is often offered through hospitals. He may also benefit from seeing a dietitian to see if he can lower his cholesterol levels through diet. After he is treated and on his way to recovery, he may wish to start a cardiac rehab exercise program to gain back his strength....
s as its contractile unit. Like smooth muscle and unlike skeletal muscle, cardiac muscle does not need to be innervated at every fiber because it can communicate electrical signals from cell to cell. This communication is achieved through intercalated discs, a feature unique to cardiac muscle....
