Vision and Light Quiz

What does vision require according to the text?

• Sensation only

• Perception only

• Both sensation and perception

• Neither sensation nor perception

What is the range of wavelengths that light travels, as mentioned in the text?

• ~150,000 km/sec

• ~300,000 km/sec

• ~450,000 km/sec

• ~600,000 km/sec

What is visible to us?

• Electromagnetic radiation with wavelength (380-390 nm)

• Electromagnetic radiation with wavelength (380-790 nm)

• Electromagnetic radiation with wavelength (380-890 nm)

• Electromagnetic radiation with wavelength (380-690 nm)

What are the three dimensions of light mentioned in the text?

• Hue, Saturation, Luminance

• Hue, Saturation, Brightness

• Hue, Intensity, Brightness

• Hue, Intensity, Luminance

What is the function of sensory receptors in the eye?

• To detect environmental stimuli and produce receptor potentials

• To detect environmental stimuli and release neurotransmitters

• To detect environmental stimuli and alter the cell's membrane potential

• To detect environmental stimuli and move the eye muscles

What is sensory transduction?

• The process where sensory stimuli are turned into receptor potentials

• The process where receptor potentials are turned into sensory stimuli

• The process where neurotransmitters are released in response to light

• The process where the eye muscles are controlled by receptor potentials

What must happen for images to be focused on the Retina?

• Images must be translated into electrical activity by the sensory receptors

• Images must be processed by the bipolar and ganglion cells

• Images must be focused on the Retina to see

• Images must be moved by the extracellular muscles

Which structures are involved in causing electrical activity in sensory receptors of the retina?

• Photoreceptor, Bipolar cell, Ganglion cell

• Bipolar cell, Ganglion cell, Sclera

• Photoreceptor, Ganglion cell, Sclera

• Photoreceptor, Bipolar cell, Sclera

What is the function of the cornea in the eye?

• It controls the amount of light that enters the eye.

• It is responsible for the blind spot because it has no receptors.

• It alters the shape of the lens by contracting the ciliary muscles.

• It mediates the most acute vision.

What is the role of the lens in the eye?

• It produces the blind spot.

• It mediates the most acute vision.

• It changes shape to allow the eye to focus on near or distant objects.

• It conveys information from photoreceptors to ganglion cells.
