6. With reference to this topic, state a brief function for theseterms:
Cerebellum Cochlear nerve Vestibulospinal tractOrgan of Corti (spiral organ)
Stapedius muscle Round window
Semicircular Canals
Auditory (Eustachian) tube
Tensor tympani m.
Tympanic membrane
Ext. Auditory canal
7. Describe the relationship between sound frequencies and thehair cells located in the cochlea.
8. Describe the role of the auricle in sound direction and collection.
9. Explain the role of otoliths in the perception of static equilibriumbased on head position.
10. Explain the role of endolymph (semicircular canals) as itrelates to the perception and activation of receptors duringangular acceleration.
11. State the differences between conductive and sensorineuraldeafness.
12. Explain the importance of the Rinne test.
13. During the Balance Test, several sensory receptors played arole. Name 3 sensory receptors. Hint: Was your balance betterwith the eyes open or closed? Why?
14. State and explain the difference between static and dynamicequilibrium.
15. Describe a step-by-step pathway of how sound enters the earand is transmitted to the spinal cord.
