Summary Introduction
To determine:
The type of muscle tissue that is least impacted by the change in extracellular Ca2+ concentration during contraction.
Introduction:
The increased amount of the Ca2+ promotes the formation of actin-myosin complex in the muscle cells. Therefore the Ca2+ concentration of the cytosol should always be low. Muscle fibers would fail to relax if the concentration of the Ca2+ remains increased. The muscle tissue that would be least impacted by the increased concentration of Ca2+ in the extracellular space in the contraction state, is the skeletal muscle tissues.

A skeletal muscle can be stimulated, under laboratory conditions, with a supramaximal stimulus. Is it possible for the muscle to respond with a supramaximal contraction? Explain
Unlike skeletal muscle smooth muscle Mayer spontaneously contract when it is. What feature of smooth muscle allows it to stretch without immediately resulting in a strong contraction?
If ACh channels are opened on a muscle fiber that is held at +55 mV, which ion moves predominantly? In which direction does this ion move across the muscle cell membrane?
