The cclea is responsible for the semicircular hearing, and vestibule and canals for the balance. Physiology the sound is a vibratory energy that penetrates in the MOTHER and happens in TM, being transmitted to the ossculos. This sonorous vibration is translated into electric energy in the internal ear, that is sent to the central nervous system with all its characteristics of intensity, frequency and harmony, reaching the brain in previous the secular turn transverso, when the sound is recognized. Semiologia of physical the Semiologia Hearing: inspection; palpao; otoscopia; examination of tuba auditory (air insufflation?
