Like nerve signals, hormones carry messages around the body.Recall how hormones are different to nerve signals.

Hormones and nerve signals are both essential for communication within the body, but they function in different ways.

1. Method of Transmission: Nerve signals are transmitted electrically along the neurons, while hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions.

2. Speed of Transmission: Nerve signals are transmitted much faster than hormones. The effects of nerve signals can be seen almost instantly, while hormones may take from a few minutes to a few hours to show their effects.

3. Duration of Effect: The effects of nerve signals are generally short-lived and stop once the signal is no longer being sent. On the other hand, hormones can have long-lasting effects, even after the initial release of the hormone has stopped.

4. Specificity: Nerve signals are sent from one specific location to another specific location. Hormones, however, are released into the bloodstream and can therefore affect multiple organs and tissues at the same time.

5. Nature: Nerve signals are electrical signals transmitted through nerve cells, while hormones are chemical substances.

In summary, while both hormones and nerve signals are crucial for body communication, they differ in their method of transmission, speed, duration of effect, specificity, and nature.
