Contractile impulse refers to the electrical signal that initiates contraction in muscle cells. In cardiac muscle, this impulse originates from the sinoatrial (SA) node, propagating through the heart to coordinate rhythmic contractions. In skeletal muscle, it results from signals transmitted by motor neurons. Overall, contractile impulses are crucial for the effective functioning of both cardiac and skeletal muscles.

The motor nerve cells control the skeletal muscle
It is called a nerve impulse.
The nerve's endings are near to other nerve endings, when the potential of the potassium ion that is released is sensed by the other nerves they all might send an impulse to their other ends and the situation could be repeated.
