Question

Sensation of vision in the retina is carried to the brain by

• A. cornea
• B. ciliary muscle
• C. optic nerve
• D. None

Answer 1

The Correct Option is C

To solve the problem, we need to identify which part of the eye carries the sensation of vision from the retina to the brain.

1. Understanding the Role of the Retina:
The retina contains photoreceptor cells (rods and cones) that detect light and convert it into electrical signals.

2. Pathway to the Brain:
These electrical signals need to be transmitted to the brain so they can be interpreted as visual images. This transmission is done by the optic nerve.

3. Functions of Other Options:
- The cornea is responsible for focusing light into the eye.
- The ciliary muscle controls the shape of the lens for focusing.
- None is incorrect as the optic nerve is the right answer.

Final Answer:
The sensation of vision in the retina is carried to the brain by the optic nerve.
