Question 14

Rods and cones, bipolar cells, ganglion cells, optic nerve

The correct visual pathway in humans begins with rods and cones, which are the photoreceptors in the retina, followed by bipolar cells that transmit signals to ganglion cells, and finally, the optic nerve carries the visual information to the brain.

A) Bipolar cells, ganglion cells, rods and cones, optic nerve

This option incorrectly places bipolar cells and ganglion cells before the rods and cones, which are the initial receptors for light. The visual pathway starts with rods and cones, making this sequence inaccurate.

B) Optic nerve, rods and cones, ganglion cells, bipolar cells

This sequence incorrectly suggests that the optic nerve comes before the photoreceptors. The optic nerve transmits visual information after processing by rods, cones, bipolar cells, and ganglion cells, so this order is fundamentally flawed.

C) Rods and cones, bipolar cells, ganglion cells, optic nerve

This option accurately reflects the correct order of the visual pathway in humans. The pathway starts with rods and cones detecting light, which then signal bipolar cells, followed by ganglion cells, and finally the optic nerve, which conveys the information to the brain.

D) Ganglion cells, bipolar cells, optic nerve, rods and cones

This option incorrectly places ganglion cells before bipolar cells and suggests that rods and cones come after the optic nerve. In reality, rods and cones are the first to process visual stimuli, making this sequence incorrect.

Conclusion

The correct answer, C, accurately describes the sequence of the visual pathway in humans, starting with the photoreceptors and ending with the optic nerve. All other options misrepresent the order of components in this crucial sensory pathway, thereby failing to reflect the actual biological process of vision.
