Electrical Impulses: is a method of transporting information of environmental change from the receptor to the coordinator in order to receive a response.
- Impulses are sent to the coordinator from the receptor.
- While making a decision, receptors are affected by an environmental change, electrical impulse is then sent to the Central Nervous system through the sensory nerves. The brain then coordinates a response.
An uncoordinated response: A reflex, Example- withdrawing your hand after touching something really hot
- Pain receptor detects the hot temperature (stimuli)
- Sensory nerve sends electrical impulse to the brain.
- The motor nerve sends signals to the effector which is the muscle in this case. The muscle then contracts and hand is withdrawn.
