In summary, excite the muscle cell. In a little more detailed summary, acetylcholine is a neurotransmitter that reversibly binds to and stimulates the muscarinic acetylcholi â¦ ne receptors on the post-synaptic region of the sarcolemma of the skeletal muscle, called the motor end plate.he result of this binding of acetylcholine to the acetylcholine receptor is opening of sodium channels and influx of sodium cations into the muscle cell, causing the resting potential of that muscle cell to begin to depolarize.

Named cells and ranges make it easy to work out what a formula does. You can name a cell or a whole range of cells to use in a formula.
