Chapter 14, Problem 2CT
Summary Introduction
To suggest: The reason why rupture of eardrum is necessary to cure a chronic middle-ear infection in Person M.
Introduction: The ear is the hearing organ that detects sound and the movements of the brain. The stimulus is transduced into nerve signals. Nerve signals are then transmitted by the vestibular nerve (eighth cranial nerve) and they result in the sensation of hearing and equilibrium. Anatomically, the ear is divided into three distinct regions, namely external ear, middle ear, and inner ear.

- Jill is diagnosed with sensorineural deafness, a disorder in which sound waves are transmitted normally to the inner ear but they are not translated into neural signals that travel to the brain. Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself. Where in the inner ear is the disruption most likely to be located?arrow_forwardFigure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forwardIn the ear, sound waves cause the tympanic membrane to vibrate. What happens next in the middle ear? In the inner ear?arrow_forward
- When you stimulate conduction deafness, why can you still hear the tuning fork when it is on your mastoid process, but not when it is near your external auditory meatus?arrow_forwardWhat is the inner ear called?arrow_forwardGrandpa can't ever seem to hear what his little granddaughters say. He also can't hear that high-pitched whine in the Subaru engine that everyone else seems to hear. You suspect that grandpa has too much ear wax built up in his external auditory canal, and therefore has developed conduction deafness has damage to the vestibulocochlear nerve has damaged either the utricle or the saccule, though it will be hard to tell which one without further testing has damaged the hair cells closest to the oval window has "selective" hearing loss, because the granddaughters are always trying to get him to play with them when he's tired, and he doesn't want to work on that darned car anymore either.arrow_forward
