A person blinks when an insect enters their eye. What causes this reflex action?
- Amuscles in the eyelid cause the eye to blink impulses are sent down the motor neurones relay neurones sensory neurones receptor cells in the cornea detect the insect
- Bmuscles in the eyelid cause the eye to blink impulses are sent down the sensory neurones relay neurones motor neurones receptor cells in the retina detect the insect
- Creceptor cells in the retina detect the insect impulses are sent down the relay neurones sensory neurones motor neurones muscles in the eyelid cause the eye to blink
- Dreceptor cells in the cornea detect the insect impulses are sent down sensory neurones relay neurones motor neurones muscles in the eyelid cause the eye to blink
