Show Answers:

  1. Pathway of light through eye
    Cornea, Iris, Pupil, Lens, Ganglion Cells, Bipolar Cells, Rods and Cones
  2. Transduction
    The process of transducing a light signal into a neural impulse
  3. Depth perception
    Involves interpretation of visual cues that indicate how near or far away objects are
  4. Binocular depth cues
    Clues about distance based on the differing views of the two eyes
  5. Retinal disparity
    Objects within 25 feet project images to slightly different locations on the right and left retinas, so the right and left eyes see slightly different views of the object
  6. Convergence
    Involves sensing the eyes converging toward each other as they focus on closer objects
  7. Monocular depth cues
    clues about distance based on the image in either eye alone.
  8. Motion Parallax
    Involves images of objects at different distances moving across the retina at different rates (fence posts compared to trees in distance while driving in car)
  9. Pictorial depth cues
    clues about distance that can be given in a flat picture
  10. External ear
    Consists of the pinna and the eardrum
  11. Pinna
    A sound collecting cone
  12. Eardrum
    A taunt membrane that vibrates in response. (waves of pressure create vibrations)
  13. Middle ear
    Vibrations of the eardrum are transmitted inward by mechanical chain- three tiniest bones in the body(Hammer, anvil, and stirrup) known as the ossicles.
  14. Ossicles
    Converts relatively large movements with little force into smaller motions with greater force
  15. Cochlea
    A fluid filled, coiled tunnel that contains the receptors for hearing
  16. Basilar membrane
    Runs the base of the spiraled cochlea, and holds the auditory receptors.
  17. Place theory
    Perception of pitch corresponds to the vibration of different portions, or places, along the basilar membrane (hair cells at various locations respond independently and to different frequencies)
  18. Frequency theory
    Perception of pitch corresponds to the rate, or frequency at which the entire basilar membrane vibrates. (the whole membrane vibrates in unison in response to sounds)
  19. Auditory localization
    Locating the source of a sound in space.
