The table below lists the steps related to the conduction of the nervous impulse. They are not in the correct order. Allot each of them a number to put them in the correct sequence. Each step is named as a letter. Identify its step number.
ASignal is passed along the sensory neuronBSignal is passed along the relay neuronCReceptor cells detect the signalDSignal is passed to the effector cells which produce the responseESignal is passed the motor neuron
C-A-B-E-D
The diagram above shows the reflex arc which is the neuralpath which controls and immediate action.
From this diagram, we can understand the order of the steps correctly.
The correct order is
1. Receptor cells detect the stimulus.
2. Signals passed along the sensory neuron.
3. Signals passed along the realay neuron.
4. Finally the signal is passed to the motor neuron.
5. Signal is passed to the effector cells which produces the response.
6. Hence correct answer is C-A-B-E-D.
