The nervous system ( ear and eye and brain)

Front

What structure in the eye is responsible for detecting color?

Back

Cones are the photoreceptor cells in the retina that detect color.

Front

What is the function of the cerebellum in the brain?

Back

The cerebellum coordinates voluntary movements, balance, and posture.

Front

What is the black portion of the eye that lets light in?

Back

The pupil is the opening in the center of the iris that allows light to enter the eye.

Front

What part of a neuron is responsible for transmitting impulses away from the cell body?

Back

The axon is the long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.

Front

What is the role of the lens in the eye?

Back

The lens focuses light onto the retina, allowing for clear vision.

Front

What are rods in the eye responsible for?

Back

Rods are photoreceptor cells that are sensitive to low light levels and are responsible for night vision.

Front

What is the main function of the retina?

Back

The retina converts light into neural signals and sends them to the brain for visual recognition.

Front

What is the role of the cornea in the eye?

Back

The cornea is the transparent front part of the eye that refracts light and helps focus it onto the retina.

Front

What is the function of the optic nerve?

Back

The optic nerve transmits visual information from the retina to the brain.

Front

What is the purpose of the myelin sheath in neurons?

Back

The myelin sheath insulates axons and increases the speed of electrical impulses.
