HORMONES IN ANIMALS

Reach: Nervous tissue does not connect all the body cells but hormones can reach all the cells of the body through the bloodstream.
Nature & Pace: Neurons transmit information at a very fast rate through electrical impulses but hormones are chemicals in nature that travel slowly.
Steadiness: Neurons take some time to reset its mechanisms before transmitting another impulse but hormonal communication can be done persistently.
