Which description best explains how the optic chiasm routes information from the visual fields?

  1. A

    The left visual field is sent to the left hemisphere, and the right visual field to the right hemisphere.

  2. B

    All fibers from the left eye cross, while none from the right eye cross.

  3. C

    Information about the left visual field is sent to the right hemisphere, and information about the right visual field to the left hemisphere.

  4. D

    Each eye sends information only to the hemisphere on the same side.

Which statement best describes the relationship between taste and flavor?

  1. A

    Flavor is determined only by taste-receptor activity.

  2. B

    Taste begins with chemicals in saliva activating taste-receptor cells, and smell also contributes substantially to flavor.

  3. C

    Smell contributes to flavor, but taste signals bypass the brainstem and thalamus.

  4. D

    Taste-receptor cells detect sound vibrations in the cochlea.

  1. A

    The anterolateral pathway; it crosses within the spinal cord

  2. B

    The dorsal column–medial lemniscus pathway; it crosses in the medulla
