Question

Quizplus · Accepted Answer

The first step is the bright light being shone into the eye (4), which triggers the retinal cells to generate action potential (1). The action potential is then conducted by the optic nerve to the CNS (5), where the visual cortex translates the action potential (3) and the person becomes aware of the information obtained by the CNS (2). Therefore, the correct sequence is 4, 1, 5, 3, 2, which is only present in choice C.
