- Nerve impulses pass through the CNS and the effectors create a respons
- Electrical impulses
- Signals/impulses created by the receptors which are send to the coordinator
- Method of transporting information of environmental change from the receptors to the coordinators in order to produce a response
- Decision making
- When receptors are affected by a change, they sends eletrical signals/impulses through the sensory nerves to the CNS
- The brain then coordinates the response
- Reflex action
- Very rapid, uncoordinated movement
- Ex: Pulling your leg up after stepping on a lego block in the dark
- Pain receptors detects the lego
- Sensory Nerve sends the electrical signal (Impulse) to the CNS, Brain
- The Motor nerve sends signals to the effector (Skin)
- The effector (Skin) produces a response
- Reflex
- Muscle contracts
- Leg is pulled up
