Which structure is involved in the process of vision by capturing light and converting it into electrical signals?

The structure that plays a crucial role in vision by capturing light and converting it into electrical signals is the retina. The retina is a thin layer of tissue located at the back of the eye, containing specialized cells called photoreceptors. These photoreceptors, specifically rods and cones, are sensitive to light. When light enters the eye, it is focused by the lens and then reaches the retina, where the photoreceptors detect the light and convert it into electrical signals. These signals are then transmitted to the brain via the optic nerve, allowing us to perceive images.

Understanding the function of the retina is vital, as it is fundamental to the entire process of vision. It is where the transformation of light into neural activity occurs, making it essential for our ability to see.
