Determine the correct order of events that occur when light strikes photoreceptor cells.
1)The bipolar cell depolarizes.
2)Action potentials are sent to the brain via the optic nerve (CN II).
3)Light hyperpolarizes the photoreceptor.
4)Retinal ganglion cell produces action potentials.

Determine the correct order of events that occur when light strikes photoreceptor cells.

4)Retinal ganglion cell produces action potentials.

Quizplus · Accepted Answer

1)When light strikes photoreceptor cells, it first hyperpolarizes the photoreceptor, which means the cell's membrane potential becomes more negative.
2)This change in membrane potential causes the bipolar cell to depolarize, leading to the activation of the retinal ganglion cell.
3)The retinal ganglion cell then produces action potentials, which are sent to the brain via the optic nerve (CN II).
Therefore, the correct order is 3, 1, 4, 2.
