Muscles, Part 1 - Muscle Cells: Crash Course A&P #21

And I talk and you sit there, eat, text and take notes, the same story repeating itself over and over again. Like watching this video over and over again to fully understand all the sections of the sliding string model. But some stories become more beautiful the more we hear them. Watch this video again to understand that smooth, cardiac, and skeletal

muscle

s allow movement by contraction and relaxation in a process called sliding filamentous pattern. Furthermore, skeletal

muscle

is formed as a rope composed of bands of protein fibers, and the smaller bands are filaments of actin and myosin. Its use of calcium adenosine triphosphate causes adhesion and separation, causing the sarcomeres to contract and relax.
