Which of the following option shows the order of events correctly when a bright light is focused on our eyes?
- a)Bright light → receptors in eyes → sensory neuronàspinal cord → motor neurons → eyelid closes
- b)Bright light → receptors in eyes → spinal cord → sensory neuron → motor neurons → eyelid closes
- c)Bright light → receptors in eyes → sensory neuron → motor neurons → spinal cord → eyelid closes
- d)Bright light → receptors in eyes → spinal cordà motor neurons → sensory neuron → eyelid closes
Correct answer is option 'A'. Can you explain this answer?

Which of the following option shows the order of events correctly when...
When a bright light is focused on our eyes, light receptors in the eyes detect the stimulus and send an impulse via sensory neurons to the spinal cord. The spinal cord then processes the information and sends a signal through motor neurons to the muscles controlling the eyelids, causing them to close. This pathway follows the correct reflex arc sequence, making option (a) the correct answer.

Understanding the Response to Bright Light
When a bright light is focused on our eyes, a series of events occur to protect our eyes and maintain visual clarity. Here’s a breakdown of the correct sequence of events:
1. Detection of Light
- Bright light stimulates the receptors in the eyes, specifically the photoreceptors (rods and cones).
- These receptors convert the light stimulus into electrical signals.
2. Transmission of Signals
- The electrical signals are transmitted via sensory neurons, which carry the information from the eyes to the brain.
3. Processing in the Spinal Cord
- The signals travel through the spinal cord where basic reflex actions are processed.
4. Activation of Motor Neurons
- The spinal cord activates motor neurons, which are responsible for sending signals to the muscles.
5. Response Execution
- Finally, the motor neurons trigger the muscles of the eyelid to close, protecting the eyes from excessive light exposure.
Conclusion
The correct order of events is crucial for a quick response to bright light, ensuring that our eyes are safeguarded from potential damage. Therefore, option A accurately represents this sequence:
Bright light → receptors in eyes → sensory neuron → spinal cord → motor neurons → eyelid closes.
Understanding these steps is vital for comprehending how our body reacts instinctively to environmental stimuli.
