What is the function between a motor neuron and a muscle fiber called?

Step-by-step solution

Increase in Ca²⁺ level leads to the binding of calcium with a subunit of troponin on actin filaments and thereby remove the masking of active sites for myosinThe globular head of the myosin filament is an active ATPase enzyme and has binding sites for ATP and active sites for actin.>The cycle of cross-bridge formation and breakage causes further sliding of actin The junction between a motor neuron and the sarcolemma of a muscle fiber is called the neuromuscular junction or motor-end plate.
