Activated by stimuli such as injury or high mechanical load satellite cells are. B A photomicrograph of cardiac muscle cells.

When muscle tension changes without any corresponding changes in muscle length the muscle contraction is.
. Muscle tension is the force exerted by the muscle on an object whereas a load is the force exerted by an object on the muscle. Figure 1921 Cardiac Muscle. Force itself can be differentiated as either tension or load.
Satellite cells are described as quiescent myoblasts and neighbor muscle fiber sarcolemma. A Cardiac muscle cells have myofibrils composed of myofilaments arranged in sarcomeres T tubules to transmit the impulse from the sarcolemma to the interior of the cell numerous mitochondria for energy and intercalated discs that are found at the junction of different cardiac muscle cells. It has been posited that skeletal muscle satellite cells SC which provide an essential role for the regeneration and repair of muscle fibres through the provision of additional myonuclei to the mature post-mitotic muscle cells Lepper et al 2011 may also play an important role in muscle growth in response to RET and muscle mass.
They are crucial for the repair of muscle but have a very limited ability to replicate. Muscle contractions can be described based on two variables.
