Our arms and fingers grow in certain directions, not haphazardly. So controlled movements can be either slow or fast. If fast responses to stimuli are to be made, information transfer must happen very quickly. For this, the medium of transmission must be able to move rapidly. Electrical impulses are an excellent means for this.
But there are limitations to the use of electrical impulses.
1. They will reach only those cells that are connected by nervous tissue, not each and every cell in the animal body.
2. Once an electrical impulse is generated in a cell and transmitted, the cell will take some time to reset its mechanisms before it can generate and transmit a new impulse. In other words, cells cannot continually create and transmit electrical impulses.
Hence, most multi cellular organisms use another means of communication between cells, namely, chemical communication.
