Question

Explain the statement: Electrical impulses are an excellent means for coordination with its own limitations.

✓

Answer

In case if a quick response to stimuli is to be made, electrical impulses are used. They are excellent means for coordination.
$\rightarrow$ The transmission of impulse in nerve fibre occurs very quickly. It is excellent for control and coordination.
But electric impulses have following limitations:
(1) Electric impulses will reach only those cells that are connected by nervous tissue.
(2) Electric impulses will not coordinate with each and every cell in the animal body.
(3) Nerve cells cannot continually create and transmit electric impulses. The cell will take some time to reset its mechanism before it can generate and transmit a new impulse.
