Question
Which is the correct sequence of the components of a reflex arc?
Options
Receptors → Muscles → Sensory neuron → Motor neuron → Spinal cord
Receptors → Motor neuron → Spinal cord → Sensory neuron → Muscle
Receptors → Spinal cord → Sensory neuron → Motor neuron → Muscle
Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle
Solution
Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle
Explanation -
Sensory neuron collect signal from the receptor in a reflex arc. This signal moves forward to spinal cord and then through the motor neuron, it reaches to muscles.
Spinal Reflex Arc
