Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which order is a signal sent from stimulus to response?
A
Sensory Organ, Sensory Neuron, Interneuron, Motor Neuron, Effector
B
Sensory Neuron, Sensory Organ, Interneuron, Motor Neuron, Effector
C
Interneuron, Sensory Neuron, Sensory Organ, Motor Neuron, Effector
D
Motor Neuron, Effector, Interneuron, Sensory Neuron, Sensory Organ
E
Effector, Motor Neuron, Interneuron, Sensory Neuron, Sensory Organ
Explanation: 

Detailed explanation-1: -Hence the correct order is: Receptor→Sensory Neuron→Spinal cord→Motor neuron→Effector.

Detailed explanation-2: -Receptors→sensory neuron→spinal cord→motor neuron→muscles. The path taken by nerve impulse in a reflex action is called a reflex arc.

Detailed explanation-3: -The correct sequence of the components in a reflex arc is given below: Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle.
