- Which of the following descriptions of photoreceptors in the eye is NOT correct? a. Cones are concentrated in the fovea of the retina and function to detect colours. b. Rods are concentrated at the periphery and function well in dim light. c. Rods are concentrated in the fovea of the retina and function well in dim light. d. Rods are sensitive to light and register black and white. Cones detect colours.arrow_forwardWhich of the following statements explains why vision is less sharp in dim light than in bright light?a. Cones are more responsive in dim light.b. There are more rods than cones in the eye.c. Many rods converge on a single ganglion.d. The dilated pupil lets in more light than the lens can focus.arrow_forwardColour blindness can result from the loss of specific types of cones, or it can occur in individuals having fewer cones of a given type. An individual has 50% less than the normal number of green cone photoreceptors in his or her retina. How would this affect his or her vision? a. This person has night blindness. He or she should start to eat more carrots to replenish the stock of retinal molecules in the retina. b. This person will have difficulty adapting to varying light levels. His or her cone receptors take much longer to adapt in a brightly lit area. c. This person does not have a colour blindness because no green cone photoreceptors are in the retina; only red, yellow, and blue photoreceptors exist. d. This person has a mild green colour blindness. He or she cannot see green colours very clearly and has difficulty distinguishing colours involving green hues.arrow_forward
- Myopia is a condition in which a person has: a. light rays focusing in front of the retina due to a flattened cornea b. light rays focusing in front of the retina due to a short eyeball c. light rays focusing in front of the retina due to a cornea that is too curved d. light rays focusing in front of the retina due to a detached retinaarrow_forwardWhich one of the following statements about photoreception is true? a. Light detection is initiated by the absorbance of light (a photon) by a photopigment molecule. b. Light detection is synonomous with vision. c. Light detection is always initiated in a rod photoreceptor located in the retina. d. Only light in the visible range (between 400 and 700 nm wavelength) can be detected by animals. e. None of the above answer choices (neither A, nor B, nor C, nor D) is true.arrow_forwardMyopia is a condition in which a person has Select one: a. light rays focusing in front of the retina due to a flattened cornea b. light rays focusing in front of the retina due to a short eyeball c. light rays focusing in front of the retina due to a cornea that is too curved d. light rays focusing in front of the retina due to a detached retinaarrow_forward
- When reading, a person with astigmatism sees some lines in sharp focus while others appear blurred. Astigmatism is caused by the a. inability of the iris to contract or dilate b. lens becoming cloudy and rigid c. number of cones on some parts of the retina being deficient d. curvature of the cornea or lens not being symmetricalarrow_forwardWhich of the following components of the eye allows a person to focus on objects at various distances? a. The optic nerve b. The sclera c. The lens d. The photoreceptor cells. e. The vitreous humourarrow_forwardWhen you exit a dark room into a brightly lit environment, within seconds, you to see a crisp view of your surroundings. However, when you enter a dark room from a brightly lit environment, your eyes might take more than 10 minutes to become used to the new surroundings. Your eyes are waiting for: a. the rods to begin to function b. the cones to begin to function c. the pupils to get smallerarrow_forward
- Which of the following statements is/are correct about the visual system? A.Input from the left eye is processed exclusively in the right V1 cortex. B. Each point in the visual field is analyzed by both the right and left V1 cortices. C. The right visual hemifield projects to the right LGN. D. Two of the above statements are correct. E. None of the above statements are correct.arrow_forwardThe human eye focuses bya. changing the thickness of the lens.b. changing the shape of the lens.c. opening and closing the pupil.d. rotating the lens.arrow_forwardWhich of the following is accurate about the maculae of the vestibular apparatus? a. They detect rotational movements of the head. b. They are located in the semicircular canal. c. Nerve signals are generated when the otolithic membrane bends the stereocilia of the hair cells. d. They are the organs of hearing.arrow_forward
