The actin and myacin molecules share electron bonds.
As the electrons are reconfigured (probably by calcium ions),
a force is generated which tries to reconfigure the position of the molicules.
The distance a muscle can shorten
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
a muscle tissue can.
your thigh because it can get floppy
True.
Muscles can contract and shorten
muscle tissue can contract and shorten
The muscle fibres are contracting
Muscle cells are the tissues that shorten and exert force. This is achieved through the sliding of actin and myosin filaments within the muscle fibers, causing them to contract and generate tension. This contraction allows muscles to exert force to produce movement or maintain posture.
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
Muscle tissue has cells that shorten to exert force. This shortening of muscle cells is what allows for movement and physical activity.
