Contractions Can Occur in Striated Muscle as Long as Ca²⁺

Essay

Contractions can occur in striated muscle as long as Ca²⁺ is present in the cytosol.As cytosolic levels of free Ca²⁺ decrease,so does the ability for myosin to form cross-bridges with actin.This leads to relaxation of the muscle.You have found a novel muscle and are trying to determine if its relaxation processes are regulated in a manner analogous to vertebrate striated muscle.Describe some of the features of Ca²⁺ regulation that you would expect to see in this novel muscle.
