Module Learning Targets: 

The Eye and Vision   1.  Describe the structure and function of accessory eye structures, eye layers, the lens, and humors of the eye.   2.  Outline the causes and consequences of cataracts and glaucoma.   3.  Trace the pathway of light through the eye to the retina, and explain how light is focused for distant and close vision.   4.  Outline the causes and consequences of astigmatism, myopia, hyperopia, and presbyopia.   5.  Describe the events involved in the stimulation of photoreceptors by light, and compare and contrast the roles of rods and cones in vision.   6.  Compare and contrast light and dark adaptation.   7.  Trace the visual pathway to the visual cortex, and briefly describe the steps in visual processing.

The Chemical Senses: Taste and Smell   8.  Describe the location, structure, and afferent pathways of taste and smell receptors, and explain how these receptors are activated.

The Ear: Hearing and Balance   9.  Describe the structure and general function of the outer, middle, and internal ears.10.  Describe the sound conduction pathway to the fluids of the internal ear, and follow the auditory pathway from the spiral organ (of Corti) to the temporal cortex.11.  Explain how one is able to differentiate pitch and loudness, and localize the source of sounds.12.  List possible causes and symptoms of otitis media, deafness, and Ménière’s syndrome     13.          Explain how the balance organs of the semicircular canal
