Question
Tracing the sequence of events when bright light is focussed on the eyes involves which type of neural response?
A hormonal-only response
A reflex response, such as pupil constriction, via a reflex arc
A purely voluntary decision
No response at all
Answer
A reflex response, such as pupil constriction, via a reflex arc
Detailed Explanation
Bright light focussed on the eyes triggers a reflex, such as constriction of the pupil, mediated through a rapid reflex arc rather than conscious deliberation.
