If a person sustains damage to axons leading from sensory receptors to the central nervous system, which step or steps of sensory perception will be affected?

Larry goes to the doctor complaining that he cant see the right side of the visual field with either eye. Where in the visual signal-processing pathway is Larrys problem occurring?

____________ is understanding what particular sensations mean.

Name six categories of sensory receptors and the type of stimulus that each type detects.

In the ear, sound waves cause the tympanic membrane to vibrate. What happens next in the middle ear? In the inner ear?

Jill is diagnosed with sensorineural deafness, a disorder in which sound waves are transmitted normally to the inner ear but they are not translated into neural signals that travel to the brain. Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself. Where in the inner ear is the disruption most likely to be located?

Figure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.

Which of the special senses is based on the following events? Membrane vibrations cause fluid movements, which lead to bending of mechanoreceptors and firing of action potentials. a. taste b. smell c. hearing d. vision

Visual stimuli in the upper-left visual field will be processed in what region of the primary visual cortex? inferior right inferior left superior right superior left

Figure 14.9 The basilar membrane is the thin membrane that extends from the central core of the cochlea to the edge. What is anchored to this membrane so that they can be activated by movement of the fluids within the cochlea? Figure 14.9 Cochlea and Organ of Corti LM × 412.
