[Answer] What is the ability of muscle cells to shorten and generate a pulling force?

Answer: contractility
What is the ability of muscle cells to shorten and generate a pulling force?

Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length such as when holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation which is a …

Muscle fatigue is the decline in ability of muscles to generate force .It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.There are two main causes of muscle fatigue: the limitations of a nerve’s ability to generate a sustained signal (neural fatigue); and the reduced ability of the muscle …
