2. Auditory Tests  For the Rinne test, a vibrating tuning fork (typically 512Hz) is placed initially on the mastoid process behind each ear until sound is no longer heard. Then, the fork is then immediately placed just outside the ear with the patient asked to report when the sound caused by the vibration is no longer heard. A normal or positive Rinne test is when the sound heard outside of the ear (air conduction or AC) is louder than that heard of the initial sound heard when the tuning fork end was placed against the skin on top of the mastoid process behind the ear (bone conduction or BC).

3.  Weber:  Conduction loss- will not hear the sound in affected ear LOUDER  Sensineural loss- will not hear the sound in affected ear  Norm: hearing of sound is equal

4. Chemoreception: 10,000 strong!  Stimulating taste buds

5. Olfactory & Taste:

6. Jelly Beans (aka skittles)… Easter candy unavailable until Friday! As you are following the procedure, I want you to be thinking about the purpose of this activity. What are you testing? Buy the skittles riddles to really try this lab!

7. Lab Conclusion: Is there really truth to the idea that smell is a key part of taste? Defend your statement using evidence from the lab and at least one reliable source to explain the physiology behind your claim. Length: One paragraph.
