What is hyperopia and astigmatism?
Presbycusis is an age-related hearing loss affecting individuals over the age of 65. Many affected
individuals have difficulty understanding words because, although they may be able to hear the
sound, they are unable to distinguish the exact words. This hearing loss is most noticeable at
higher frequencies.
Which of the following statements correctly describes an individual suffering from presbycusis?
Select one:
a. Individuals with presbycusis have damaged hair cells at the base of the cochlea, which is
closest to the oval window.
b. Increasing the volume of higher frequency sound allows individuals affected with
presbycusis to hear better.
O c. Individuals with presbycusis have damaged hair cells at the apex of the cochlea, which is
farthest from to the oval window.
Od. Decreasing the amplitude of lower frequency sound allows individuals affected with
presbycusis to hear better.
Define the term presbyopy?

- Explain why a person may experience the sensation of “ear popping” soon after riding an elevator from the 1st floor to the 33rd floor of a tall building. Make sure you discuss how and why the shape of the eardrum changes during the ascent and what then happens to cause “ear popping.” Your answer should briefly touch on the physiology of ear popping. Could a person experience “ear popping” soon after riding an elevator down from the 33rdto the 1st floor? Why or why not.arrow_forwardThe highest density of cone cells is found in: a. the crista ampullaris. b. the optic disc. c. the fovea centralis. d. the chorion. e. the basilar membranearrow_forwardWhich of the following statements concerning the inner ear is TRUE? Question 3 options: a) The bony labyrinth within the tempoal bone contains spaces for the semicircular canals and the cochlea. b) The fibers of the cochlear nerve are attached to hair cells in the semicircular canals to carry information about movements of the head. c) The frequency of sound waves as defined by their wavelengths are perceived as pitch and are measured in decibels (dB). d) The saccule and utricle are critical sensory receptors for interpreting language, distinct from other sounds.arrow_forward
- What are the major similarities and differences in the origin and development of the three major sense organs: olfactory, optic, and auditory?arrow_forwardEpisode 3 Right before the appointment, Tina noticed that she is suffering from intense double vision when looking to objects. The double vision was less intense when looking forward, and her vision when looking left was unaffected. Her husband noticed that her right eye appeared to be turned slightly inward when she looked straight ahead. A day later, Tina noticed that the vision in her left eye started to blur. The neurologist later suggested that the two visual problems she was experiencing were related. The double vision when looking right was found to be caused by cranial nerve palsy—a form of muscle paralysis caused by a dysfunction in one of the cranial nerves. The problem with the left eye was diagnosed as optic neuritis (inflammation). Both of these signs and symptoms, along with the previous episodes, pointed to a diagnosis of multiple sclerosis (MS). The neurologist prescribed oral steroids and ordered an MRI. As with her previous episodes, Tina’s visual symptoms began to…arrow_forwardHow does the function of the semicircular ducts differ fromthe function of the saccule and utricle?arrow_forward

- What is the cochlea responsible for?arrow_forwardTinnitus 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 deafnessarrow_forwardwhy do some patients suffering from cerebral palsy also suffer from hearing and eyesight deficiencies?arrow_forward
