What is the main function of the spinal cord?

Back

The spinal cord transmits signals between the brain and the rest of the body, coordinating reflexes and processing information.

Front

What are photoreceptors?

Back

Photoreceptors are specialized cells in the retina of the eye that detect light and convert it into electrical signals for the brain.

Front

What is the role of the iris in the eye?

Back

The iris controls the size of the pupil and thus regulates the amount of light that enters the eye.

The peripheral nervous system consists of all the nerves outside the brain and spinal cord, connecting the central nervous system to the limbs and organs.

Front

What is the function of the retina?

Back

The retina is the light-sensitive layer at the back of the eye that contains photoreceptors and converts light into neural signals.

Front

What is the difference between rods and cones in the eye?

Back

Rods are photoreceptors that detect low light levels and are responsible for night vision, while cones detect color and are active in bright light.

Front

What is the function of neurons?

Back

Neurons are specialized cells that transmit information throughout the body via electrical and chemical signals.
