Eyes and Ears • Most impact • Proprioception (posture, equilibrium movement) – is maintained by ears and eyes • Eyes and ears send messages to cerebellum in relationship to coordination & perception and provide feedback for movements of the body in space (think of a baby’s head wobble – not related to the neck muscles)
Parts is Parts -- EYES • Eye parts • Outer protection - sclera, cornea, iris, ciliary body • Inner area - retina • Alterations of parts • Presbyopia, hyperopia, myopia, astigmatism, macular degeneration, cataracts, glaucoma, conjunctivitis, corneal abrasions, detached retina; retinopathy

The Ears Have it! • Hearing tests (audiometry, tympanogram, functional hearing) • Weber test • Physical exam • Platform posturography • Sinusoidal harmonic acceleration (rotary chair)
