The change in membrane potential occurring in nerve, muscle, or other excitable tissue when excitation occurs. action potential. A momentary change in electrical potential on the surface of a neuron or muscle cell. Nerve impulses are action potentials.
All of this activity requires energy. Muscles use energy in the form of ATP. The energy from ATP is used to reset the myosin crossbridge head and release the actin filament. To make ATP, the muscle does the following: 1  Breaks down creatine phosphate, adding the phosphate to ADP to create ATP.et's take a look at what occurs within a skeletal muscle, from excitation to contraction to relaxation 1  : An electrical signal (action potential) travels down a nerve cell, causing it to release a chemical message (neurotransmitter) into a small gap between the nerve cell and muscle cell.
