It is suggested that calcium and sodium ions can make an additive contribution to the overshoot potential by carrying the inward current Barium ions nad depolarizing currents affect the neurones in a manner indicative that one role of calcium is to stabilize the membrane structure Importance of Calcium Ions Ca2 ions play an important role in muscle contraction by creating interactions between the proteins myosin and actin The Ca2 ions bind to the C component of the actin filament which exposes the binding site for the myosin head to bind to in order to stimulate a muscle contraction Calcium ions play a critical role in most if not all cellular processes It has even been demonstrated that Ca2 See Answer
