Across
- 2. Height of a sound wave
- 3. The tendency for sensory receptors to decrease in response to stimuli that continue at the same level
- 4. nerve Carries information from the retina to the brain
- 7. Provides information on the position of your body by sensing gravity and motion
- 9. a theory describing how pain signals open a neurological “pain gate” in the spinal cord and how other touch signals close the gate
- 10. An opening in the iris that allows light to enter the eye
- 11. Sensory receptor organs that contain the receptor cells for taste
