Describe how a human muscle is organized. How does the structure of the muscle reflect the function?

2 Answer

  • skeletal and cardiac muscle cells are striated which means that there is overlap between actin and myosin filaments
  • Answer:

    Human muscles have a different organization depending on whether it is smooth, skeletal or cardiac muscle. Skeletal muscles have elongated, cylindrical and multinucleated type fibers, being anchored to the bones determines their function in movement.

    smooth muscles are shaped in spindle and are found around the organs of the body, forming the walls of the viscera,  this location determines its function besides they are involuntary type muscles.

    Finally, the fibers of the heart muscle are elongated, cylindrical and branched, it is located in the contractile wall of the heart and its function is to pump the heart through the movement of the muscles
