You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above

Which of the following best describes the function of a camera type eye?     A) To form high-definition images that are transmitted to the brain.     B) To gather and concentrate light through a lens onto retinal tissue which generates an impulse that is transmitted to the brain.     C) To protect the optic nerve which generates an impulse that is transmitted to the brain.     D) To detect vibrations through the vitreous body which generates an impulse that is transmitted to the brain.

The order in which the cells in the eye process light is __________. A) photoreceptors; ganglion cells; bipolar cells B) ganglion cells; bipolar cells; photoreceptors C) photoreceptors; bipolar cells; ganglion cells D) bipolar cells; photoreceptors; ganglion cells

Which of the following statements about photoreceptors is true? A) There are more rod cells in the fovea of the eye, although overall there are more cones in the human eye. B) All of these options C) Photoreceptors are located near the front of the eye, in the cornea. D) There are two types of photoreceptors, rods and cones, that contain different photopigments.

g) A person's eyes also dilate when they get drunk. What effect does this have on vision (not to mention judgment)? h) What is the pupil of the eye? i) Explain why the crystalline lens of the eye gets a virtual object from the cornea.

7. From back to front, the order of the cells in the retina are... A) Ganglion cells, photoreceptor cells, bipolar cells B) Photoreceptor cells, ganglion cells, bipolar cells C) Photoreceptor cells, bipolar cells, ganglion cells D) Ganglion cells, bipolar cells, photoreceptor cells

3. Soru Which of the following is a false statement about photoreceptors of the eye? A) Cones are active at high light levels and have high spatial acuity. B) Rods are responsible for scotopic vision while cones are responsible for photopic vision. C) Rods are active at low light level and have low spatial acuity. D) There are two types photoreceptors: rods and cones. E) The ratio of rods to cones in the retina is higher in humans than it is in dogs.

When the ciliary muscle is contracted, the following will: a) lens to become more spherical b) pupil to be dilated c) pupil to contract d) the lens to be flattened

Who proposed the “trichromatic theory” of color vision, suggesting that color perception is based on the activity of three types of cones sensitive to different wavelengths of light?a) Hermann von Helmholtz b) Gustav Fechner c) Ernst Weber d) David Hubel.

Damage to the right optic nerve would result in what type of visual field deficit?   Question 6 options:   A)  Blindness in the majority of the left visual field (both binocular and monocular)   B)  Blindness in the majority of the right visual field (both binocular and monocular)   C)  Blindness in the majority of both monocular visual fields   D)  Blindness in the binocular visual field   E)  Blindness in the majority of the right monocular visual field   F)  Blindness in the majority of the left monocular visual field
