10 the nerve that carries neural impulses from the

the lens focuses the image of distant objects in front of the retina.

10. The nerve that carries neural impulses from the eye to the brain. _________________

11. The distance from the peak of one light or sound wave to the peak of the next. It
determines color with respect to light waves and pitch with respect to sound waves.

12. Retinal receptors that detect black, white, and gray. They are necessary for peripheral and
twilight vision. _____________________
13. The central focal point in the retina, around which the eye’s cones cluster.
_______________________
14. The sense of hearing. _____________________
15. The part of the ear containing the cochlea, semicircular canals, and vestibular sacs.
_____________________ _________________
16. The principle that one sense may influence another, as when the smell of food influences
its taste. _____________________ ______________________
17. The process by which the eye’s lens changes shape to focus the image of an object on the
retina. ___________________________
18. Nerve cells in the brain that respond to specific features of the stimulus, such as shape,
angle, or movement. ___________________ ___________________
19. The theory that links the pitch we hear with the place where the cochlea’s membrane is
stimulated. ___________________ ________________
20. The minimum stimulation needed to detect a stimulus 50% of the time.
________________________ ________________________
21. Hearing loss caused by damage to the mechanical system that conducts sound waves to
the cochlea (i.e., damage to the tiny bones in the ear or the eardrum).
_________________________ ________________________
22. The system for sensing the position and movement of individual body parts.
____________________________
23. Diminished sensitivity as a consequence of constant stimulation.
_________________________ ________________________
24. In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve
matches the frequency of a tone, thus enabling us to sense its pitch.

25. The theory that the retina contains three different color receptors – one most sensitive to
red, one to blue, and one to green – which when stimulated in combination can produce
the perception of any color. ___________________________ _____________________
____________
26. Receptor cells that are concentrated in the fovea of the retina and that function in daylight
or in well-lit conditions. They detect fine detail and give rise to the perception of color.
________________________
27. The conversion of one form of energy into another. In sensation, the transforming of
stimulus energies into neural impulses. _____________________________
28. The point at which the optic nerve leaves the back of the eye. No receptor cells are
located there. _______________________
