Question
Axons of which cells in the retina form the optic nerve?a) Amacrine cellsb) Photoreceptor cellsc) Horizontal cellsd) Ganglion cellse) Bipolar cells
Solution
d) Ganglion cells
The axons of the ganglion cells in the retina form the optic nerve. Here's a step-by-step explanation:
-
Light first hits the photoreceptor cells (rods and cones) in the retina. These cells convert light into electrical signals.
-
These electrical signals are then passed onto the bipolar cells.
-
The bipolar cells then transmit these signals to the ganglion cells.
-
The axons of these ganglion cells bundle together to form the optic nerve.
-
The optic nerve then carries these signals to the brain, where they are interpreted as visual images.
So, the correct answer is d) Ganglion cells.
