How responses can be controlled by Nervous or by Hormonal Communication and the differences between the two systems
The Nervous System
- Controls your actions and co-ordinates the different parts of your body so that they are able to bring around the correct responses.
- Co-ordinates our muscles so we able to do things such as blink, breath, or swallow.
The Hormonal System
- Chemicals produced by glands in the body and are carried around by the blood.
- They also tell the body how to respond.
Differences
- Nervous System passes along information as electrical impulses.
- Hormonal System passes information as chemical messengers in the blood.
- Nervous System effects are rapid and short-lived.
- Hormonal System effects are usually slow and long-lasting.
- Nervous System effects particular organs.
- Hormonal Systems effects the whole of the body.
- Nervous Systems often involve reflexes.
- Hormonal Systems involve the control of growth, development, metabolism and reproduction.
