Chapter 9, Problem 3CSL
Jackie visits her physician because she is experiencing pain by her right ear. The doctor checks her ears and sees no sign of infection. She asks Jackie to open and close her mouth while she palpates the portions of her face adjacent to her ears. Why is the doctor having Jackie move her mouth, when she is experiencing ear pain? How may the two be related? What do you think the doctor will discover when Jackie opens and closes her mouth?

When 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.
1.) The middle ear chamber is an air-filled “hole in the head”, which is adapted to allow free movement of the tympanum as it vibrates. Unless the pressure in the chamber is equal to atmospheric pressure outside, the tympanum will be stretched outward or inward, impeding its vibration and causing discomfort or pain. When moving up in the elevator of a tall building, the surrounding atmospheric pressure is:
a) increasing causing air to enter the middle ear chamber through the Eustachian tube.
B.) increasing causing air to enter the middle ear chamber through the auditory canal
C.)decreasing causing air to leave the middle chamber through the Eustachian tube
D.) decreasing causing air to leave the middle ear chamber through the auditory canal
Answer the following:

- 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 deafnessarrow_forwardLabel the following numbers: 32, 35, 37 & 40 of the inner ear (B) and cochlea in transverse position (C)arrow_forwardthe sound of a vibrating tuning fork is perceived longer when the stern of the fork is placed against the mastoid process of the temporal bone than when the lines are placed near the patient's ear. This finding is compatible with damage to which of the following structures ? A) cochlea B) cochlear nucleus C) ossicles D) primary auditory cortex E) vestibulocochlear nervearrow_forward
- Select the best answer or answers from the choices given: The structure that allows pressure in the middle ear to be equalized with atmospheric pressure is the (a) pinna, (b) pharyngotympanic tube, (c) tympanic membrane, (d) oval window.arrow_forwardA child was involved in an automobile collision. She was not wearing a safety restraint,and her chin struck the dashboard hard.When the physician looked into her ear, hecould see into her throat. What do you inferfrom this about the nature of her injury?arrow_forwardDamage to the archways affects the ability to perceive: a) movements of the head b) head position c) sound d) all of the above optionsarrow_forward

How does this infection affect the ears?arrow_forwardWhat is the indicated organ the white arrow is pointing to?arrow_forward
- Mark the following statements as true or false. If a statement is false, correct it to make a true statement. a. The incus is connected to the tympanic membrane. b. The stapes is attached to the oval window. c. The auditory canal is separated from the middle ear by the round window. d. The cochlear duct is filled with perilymph. e. The semicircular ducts are connected to the utricle, and the cochlear duct is continuous with the saccule. f. The spiral organ is located in the scala tympani.arrow_forwardSelect the best answer or answers from the choices given: Olfactory nerve filaments are found (a) in the optic bulbs, (b) passing through the cribriform plate of the ethmoid bone, (c) in the optic tracts, (d) in the olfactory cortex.arrow_forwardOtotoxic drugs are drugs that may damage the cochlea, auditory nerve and/or the vestibular system of the ear. The damage caused is usually temporary and symptoms improve once the patient stops taking the drug. However, in some patients, the damage is permanent. Damage to the cochlea is the most common problem associated with these drugs. The reason that hearing loss results when the cochlea is damaged is: Select one: a. The bones in the ear do not amplify or increase the sound vibrations. b. The eardrum cannot transmit vibrations from sound waves to the malleus. c. The Eustachian tube remains open. d. Hair cells within the damaged cochlea do not bend preventing the transmission of an electrical signal to the auditory nerve.arrow_forward
