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

Question

Quizplus · Accepted Answer

The correct pathway of nerve impulses from the eye to the brain is receptor cells in the retina, which then activate bipolar cells, which then activate ganglion cells. These ganglion cells combine to form the optic nerve, which carries the impulses to the visual cortex in the brain. Therefore, the correct sequence is receptor cells, bipolar cells, ganglion cells, and optic nerve. This matches option A.
