asf;dasdf
| Question | Answer |
|---|---|
| Auricle | outer funnel like structure which helps to collect sound waves traveling through the air and to direct them to the ear canal or exernal auditory meatus |
| External Auditory Meatus | ear canal, s-shaped tube (ear canal) directing sound waves to the eardrum |
| Tympanic membrane | eardrum, moves back and forth in response to pressure exerted on it by sound waves and thus produces the vibrations of the sound wave source |
| Middle ear | air filled space in temporal bone |
| Malleus, incus, stapes | the three ear ossicles or ear bones, connect eardrum to inner ear. They vibrate and then create movement in inner ear fluid. |
| Semicircular canals | provide the sense of equilibrium contributing to balance |
| Vestibular nerve | carry nerve impulses to the temporal lobe of the brain for interpretation |
| Cochlea | primary ear part functioning in hearing by conversion of sound waves into nerve impulses |
| Organ of Corti | contains hearing receptors called hair cells, which function like neurons converting sound waves into nerve impulses. |
| Cochlear nerve | carries nerve impulses to temporal lobe of brain for interpretation |
