compare electrical impulse with respect to chemical impulse
Answers
Answer:
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurones, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells.
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer.
This means that communication is faster when using the nervous system.
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread.
Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.

Answer:
Electrical conduction:
a. Electrical conduction takes place through the nervous system.
b. Electrical impulses are meant for specific cells that are connected to the nervous system.
c. The electrical conduction is very quick and results in an almost immediate response.
Chemical conduction:
a. Chemical conduction is a slow process as compared to electrical conduction.
b. Chemical impulses reach every part of the body and have nothing to do with the nervous system of the body.
c. Chemical impulses are carried by blood to the body parts.
d. The hormones are responsible for chemical conduction in the body.
