In order to stimulate an effector in a toe, which pathway does a nerve impulse follow after it is initiated at a receptor?.

A stimulus is detected by a receptor
2) The receptor initiates a nerve impulse in the sensory
nerve.
3) The sensory nerve passes the message/impulse onto an
interneuron/Relay Neuron.
4) The interneuron/relay neuron passes the electrical impulse on
a motor nerve.
5) The motor nerve passes the impulse
onto the effector muscle.
6) The effector muscle carries out the response .

The correct answer is wood^4
