Module 15.5 Physiology of Vision Learning Outcomes
  1. Describe how light activates photoreceptors.
  2. Explain how the optical system of the eye creates an image on the retina.
  3. Compare the functions of rods and cones in vision.
  4. Trace the path of light as it passes through the eye to the retina and the path of action
    potentials from the retina to various parts of the brain.
  5. Explain the processes of light and dark adaptation.
Module 15.6 Anatomy of the Ear Learning Outcomes
  1. Describe the structure and function of the outer and middle ear.
  2. Discuss the role of the pharyngotympanic tube in draining and equalizing pressure in the
    middle ear.
  3. Describe the structure and function of the cochlea, vestibule, and semicircular canals in
    the inner ear.
Module 15.7 Physiology of Hearing Learning Outcomes
  1. Describe how the structures of the outer, middle, and inner ear function in hearing.
  2. Trace the path of sound conduction from the auricle to the fluids of the inner ear.
  3. Trace the path of action potentials from the spiral organ to various parts of the brain.
  4. Explain how the structures of the ear enable differentiation of the pitch and loudness of
    sounds.
Module 15.8 Vestibular Sensation Learning Outcomes
  1. Distinguish between static and dynamic equilibrium.
  2. Describe the structure of the maculae, and explain their function in static equilibrium.
  3. Describe the structure of the crista ampullaris, and explain its function in dynamic
    equilibrium.
Module 15.9 How the Special Senses Work Together Learning Outcomes
  1. Summarize the pathways for each of the special senses.
  2. Describe how the frontal lobe and limbic system integrate the signals from the special
    senses into a meaningful picture of a situation.
