  8. Structures of the Ear:
    When sound waves strike the TYMPANIC MEMBRANE in, they vibrate 3 tiny bones:

    Hair Cells
  14. There are 2 pitch perception theories:
    • 1: Place Theory
    • 2: Frequency Theory
  15. According to the _____ theory, the BASILAR MEMBRANE resembles the strings of a piano in that each area along the membrane is tuned to a specific frequency.
  16. According to the _____ theory, the BASILAR MEMBRANE vibrates in synchrony with a sound, causing auditory nerve axons to produce action potentials at the same frequency.
  17. This is commonly called "Tone-Deafness" and is the impaired detection of frequency changes.
  18. This is commonly known as "perfect pitch", which is the ability to hear a note and identify it.
    Absolute Pitch
  19. A1 is known for ________. It is in the Superior Temporal Cortex.
    Primary Auditory Cortex
  20. The Auditory System has a "what" pathway sensitive to patterns of sound in the _______ temporal cortex.
  21. The Auditory System has a "where" pathway sensitive to patterns of sound location in the ________ temporal cortex and the ________ temporal cortex.
    Posterior, Parietal
  22. The _________ temporal cortex includes areas important for detecting visual motion and the motion of sounds.
  23. Visual Cortex Structure
    • ~ Eye
    • ~ Rods & Cones
    • ~ Optic Nerve
    • ~ Occipital Lobe
    • ~ Superior Colliculous
    • ~ Lateral Geniculate
    • ~ Visual Cortex
  24. Auditory Cortex Structure
    • ~ Ear
    • ~ Hair Cells
    • ~ Auditory Nerve
    • ~ Temporal Lobe
    • ~ Inferior Colliculous
    • ~ Medial Geniculate
    • ~ Auditory Cortex
  25. A1 responds to ______ objects.
  26. The 2 categories of Impairment are:
    • 1) Conductive = Middle Ear
    • 2) Nerve Deafness = Inner Ear
  27. Diseases, infections or tumerous bone growth can prevent the middle ear from transmitting sound waves properly to the cochlea resulting in...
    Conductive (middle ear) Deafness
  28. Damage to the cochlea, the hair cells, or the auditory nerve results in...
    Nerve (Inner ear) Deafness
  29. The Visual cortex is essential for ______ ______.
    visual imagery
  30. The Auditory Cortex is essential for _____ ______.
    Auditory imagery
  31. Each cell in the A1 responds best to a particular frequency of tones, although many respond better to a _______ tones than to a single frequency.
  32. Areas bordering the ______ analyze the meaning of sounds.
  33. ______ may result from damage to the nerve cells or to the bones that conduct sounds to the nerve cells.
  34. We localize ____ frequency sounds according to differences in loudness between the ears.
  35. We localize ____ frequency sounds on the basis of differences in phase.
  36. _______ localization depends on responses of both ears
  37. Sound Localization has 3 cues:
    • 1: Sound Shadow
    • 2: Time of Arrival
    • 3: Phase Difference
  38. The vestibular organ consists of the:
    • Saccule
    • Utricle
    • 3 Semicircular canals
  39. The Vestibular receptors are modified ______ receptors.
  40. The 3 Semicircular Canals are filled with a jelly like substance and lined with _____ ____.
    hair cells (activated)
  41. The ___________ system, the sensation of the body and its movements, is not one sense but MANY, including discriminative touch, deep pressure, cold, warmth, pain, itch, tickle, and the position and movement of joints.
  42. This detects sudden displacements or high frequency vibrations on the skin.

    "Touch Receptor"
    Pacinian Corpuscle
  43. Inside the outer structure of the Pacinian Corpuscle is the ________ _______.
    Neuron Membrane
  44. There are how many spinal nerves in the brain?
    31 Spinal Nerves
  45. Each spinal nerve in the brain has a sensory and _____ nerve
  46. Axons have little or no ______ _____, which impulse travels slowly.
    Myelin Sheath
  47. 3 Aspects of Pain
    • Sensory Pain
    • Cognitive Evaluation
    • Emotion Evaluation
  48. Information from touch receptors in the head enters the _____ _____ ____ through the cranial nerves.
    Central Nervous System
