Question

The path taben by the light striking the retina will be:

• A. Sensory nerves $\to$ Ganglionic cells $\to$ Bipolar neurons $\to$ Photosensory cells
• B. Photosensory cells $\to$ Ganglionic cells $\to$ Bipolar neurons $\to$ Sensory nerves
• C. Photosensory cells $\to$ Bipolar neurons $\to$ Ganglionic cells $\to$ Sensory nerves
• D. Sensory nerves $\to$ Bipolar neurons $\to$ Ganglionic cells $\to$ Photosensory cells

Answer 1

The correct option is C Photosensory cells $\to$ Bipolar neurons $\to$ Ganglionic cells $\to$ Sensory nerves

The light first strikes primarily on photosensory cells which pass the impulse to bipolar neurons through which it moves to ganglionic cells. The direction is:
Photosensory cells $\to$ Bipolar neurons $\to$ Ganglionic cells $\to$ Sensory nerves
