- What is the role in vision of thecistrans isomerization of retinal?The correct pathway of activation (by sending neuronal signals) in the retina is bipolar cell - retinal ganglion cell - photoreceptor photoreceptor - retinal ganglion cell - bipolar cell retinal ganglion cell - bipolar cell - photoreceptor photoreceptor - bipolar cell - retinal ganglion cell O bipolar cell - photoreceptor - amacrine cellUsing a line diagram, show how parallel rays of light are brought to a focus on the retina. Explain how this focus is maintained as the distance from the object to the eye is increasedor decreased (that is, explain accommodation).
