- Meniere's disease is a disorder of the inner ear that may be due to an increase in the amount of endolymph. What would be some symptoms of this disease? Since the disease affects the inner ear and endolymph, it would probably limit the ability to equalize pressure and cause pain. Since the disease affects the inner ear, it would probably cause nausea and migraines. Since the disease affects the inner ear, it would probably cause issues with taste. Since the disease affects the inner ear, it would probably cause issues with balance and a sensation of vertigo. It could also cause hearing loss if it affected the cochlea.Vibrations in the eardrum are transmitted by the Eustachian tube to the oval window. a. False O b. TrueWhich of the following statements is FALSE? Question 40 options: Olfactory epithelium covers the superior portion of the middle and all of the superior nasal conchae as well as the cribriform plate The vomer and perpendicular plate of the ehtmoid form the majority of the bony nasal septum The stapes neatly fits into the round window of the cochlea Simply put: the cochlea is used for hearing while the semicircular canals are used for balance
- Tinnitus produces a ringing sound in the ear, although no external sound is actually present. It is a symptom that manifests from various underlying conditions of the ear. One condition that leads to tinnitus is earwax impaction. Many individuals use cotton swabs to clean the auditory canal daily. Instead of removing the earwax, cotton swabs tend to push the earwax farther into the auditory canal, causing the earwax to accumulate in the ear. This may result in tinnitus and decreased ability to hear. Earwax impaction in the auditory canal will Select one: a. lead to the loss of hair cells in the organ of Corti b. lead to perception deafness c. damage the ossicles d. lead to conduction deafnessthere is profuse anastomosis between the branches of the two internal carotid arteries and the two vertebral arteries to supply to the retina O true O FalseWhich is usually better in a person with normal hearing—air conduction or bone conduction? Why?
- Why is the force exerted on the oval window greater than that exerted on the tympanic membrane during sound transmission?Explain why it is often possible to “taste” medications, such as eyedrops,that have been placed into the eyes. Why does a person’s nose “run”when he or she cries?Because of air pressure variations due to sound wave enters the ear, this lead to establish forces cause the eardrum to vibrate. O False O true
- Alveolar edema and pooling of secretions may result to: Dull percussion note Flat percussion note Tympanic percussion note Resonant percussion noteWhich of the following structures is affected by acute otitis media? O middle ear O brynx O pharynx O alveoliWhen Maddie’s physician examines her ear, he explains to her parents that she has a perforated eardrum. Which of the following statements is NOT true? Maddie is at higher risk for ear infections due to the perforation. Maddie’s eardrum will likely heal on its own and she will not need surgery. A perforated “eardrum” means that there is a tear or hole in Maddie’s tympanic membrane. Maddie has sensorineural hearing loss due to the perforated eardrum.
