1] Nervous System Mechanisms:

● The information is conveyed in the form of electric impulse.

● The axons and Dendrite transmitted the information through a coordinated efforts.

● The flow of information is rapid and the response is quick.

● It's effects are short lived.

2] Hormonal System Mechanisms:

● The information is conveyed in the form of chemical messengers.
