What is the phisological affect of muscle tension when Ca++ is injected into the thousands of muscle fibers?

Answer 1

Ca2+ binds to troponin if the concentration in the sarcoplasm rises above 10^-6 molar and activates muscle contraction. When Ca2+ attaches to troponin, the troponin-tropomyosin complexes shift position. The cross bridges can then attach to actin, produce a power stroke, and detach from actin. This will go on as long as the Ca2+ is attached to the troponin. This will happen until the Ca2+ is transported out of the muscle membane surface.

Answer 2

it will lead to severe contraction may be followed by paralysis
