Question

Write 2 limitations of electrical impulses.

Answer 1

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.
