Presentation Transcript

  1. Auditory Sense (Hearing) Sense organs: ear, cochlea Receptor cell: hair cell, cilia deflect w/sound wave Receptor mechanism: mechanically-gated cation channels allow depolarize in one direction, hyperpol in other Coding of intensity and direction: amount and direction of cilia bending, ear coordination Coding of pitch: which hair cells are deflected Pathway of conduction: CN VIII-medulla-thalamus-auditory cortex

  2. Overall anatomy of the human ear * external ear (air) * middle ear (air) * inner ear (liquid)

  3. vestibular cochlear tympanic

  5. Equilibrium Sense organs: semicircular canals with ampullae and utricle and saccule with maculae Receptor cell: hair cell Receptor signal transduction mechanism: cilia with mechanically-gated cation channels allow depolarize in one direction, hyperpol in other Coding of intensity and direction: amount and direction of cilia bending Pathway of conduction: CNVIII-pons-cerebellum

  6. The semicircular canals - detect rotational (angular) acceleration
