When working out, knowing what stretches your muscles can take on is important so you don't tear or strain muscles :)
A nerve impulse is a way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell.
A nerve impulse travels from the dendritic end towards the axonal end. The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a dendrite of another neuron. A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells.
