1. Facts: The major equilibrium pathways projects to the cerebellum . Some information is also processed in the cerebrum . Integration and Analysis: Not applicable .2.Facts: The middle ear consists of malleus , incus and stapes, bones that vibrates with sound .The hearing portion of the inner ear consists of hair cells in the fluid -filled cochlea. The cochlear (auditory ) nerve leads to the brain. Integration and Analysis: Subjective tinnitus could arise from a problem with any of the structures named. Abnormal bone growth can affect the middle ear bones. Excessive fluid accumulation in the inner ear will affect the hair cells . Neural defects may cause the cochlear nerve to fire spontaneously ,creating the perception of sound.
