A) ganglion cells, bipolar cells, photoreceptor cells, optic nerve
B) bipolar cells, receptor cells, ganglion cells, optic nerve

Question

Which of the following sequences correctly indicates the pathway of nerve impulses on their way from the eye to the brain?
A) ganglion cells, bipolar cells, photoreceptor cells, optic nerve
B) bipolar cells, receptor cells, ganglion cells, optic nerve
C) photoreceptor cells, bipolar cells, ganglion cells, optic nerve 
D) photoreceptor cells, bipolar cells, optic nerve, ganglion cells

Quizplus · Accepted Answer

Photoreceptor cells detect light and send signals to bipolar cells, which in turn send signals to ganglion cells. The axons of the ganglion cells form the optic nerve, which carries the signals to the brain. Therefore, the correct sequence of nerve impulses is photoreceptor cells, bipolar cells, ganglion cells, optic nerve.
