Batch 2015[edit]

  1. Several questions about the tracts: which ones carry proprioception, temperature, fine and dull touch, auditory/vestibular, etc.
  2. Several questions about a combination of hearing test results and what they mean.
  3. The order in which sound travels: round window, stapes, malleus, incus, tympanic membrane, endolymph, perilymph.
  4. How does sound dissipate? Via the perilymph, via the air, etc.
  5. How to differentiate between a low-pitched male voice and a high pitched female voice? By different processing areas in the brain, by frequency, by intensity, by amplitude.
  6. Visible range of light? 400-700 nm.
  7. Shorter than 400 nm? Ultraviolet.
  8. Which cranial nerves have nothing to do with the eye? Nerve I.

  10. How can the finger discriminate between two points better than the neck? Narrow receptive field, larger area of the brain representing the finger.
  11. Synapse between second and third order neurons occurs in?
  12. Sympathetic response: dilator muscle contracts.
  13. What happens after long periods of being in the dark? Rhodopsin degrades less.
  14. What structure controls how much light enters the eye? Pupil, iris, ciliary muscle.
  15. Far vision: Cone.
  16. Touch receptor uses: mechanically gated channel.

Batch 2014[edit]

  1. Third order soma is found in thalamus.
  2. Fast pain, neothalamic something.
  3. Sympathetic: dilator muscle contracts.
