Accepted Answer

The most typical feature of Ménière's disease is vertigo, which can last from minutes to hours and is usually accompanied by hearing loss, tinnitus, and a feeling of fullness or pressure in the ear. Deafness and otosclerosis may be associated with hearing loss, but they are not specific to Ménière's disease. Strabismus and acoustic hallucinations are not typical features of the disease.

Accepted Answer

Neural hearing loss is associated with multiple sclerosis due to demyelination affecting the auditory pathways in the central nervous system.

Question 5

What type of tumor accounts for most tumor-related hearing loss?&#10;A) Squamous cell carcinoma of the auricle&#10;B) Basal cell carcinoma of the external ear&#10;C) Acoustic neuroma of cranial nerve VIII&#10;D) Neurilemoma of cranial nerve VII&#10;E) Pituitary adenoma

Accepted Answer

Acoustic neuroma, also known as vestibular schwannoma, arises from the Schwann cells of the vestibular portion of the VIIIth cranial nerve. This type of tumor is the most common cause of tumor-related hearing loss.

Question 6

The ear is connected to the nasopharynx by the:&#10;A) Internal auditory canal&#10;B) External auditory canal&#10;C) Tympanic membrane&#10;D) Eustachian tube&#10;E) Stapes

Accepted Answer

The Eustachian tube connects the middle ear to the nasopharynx, allowing air to flow between them and helping to equalize pressure on both sides of the eardrum. The internal and external auditory canals and the stapes are all part of the ear's anatomy, but they do not connect the ear to the nasopharynx. The tympanic membrane, also known as the eardrum, separates the outer ear from the middle ear.

Question 7

The tympanic cavity is part of the:&#10;A) Auricle&#10;B) External ear&#10;C) Auditory meatus&#10;D) Middle ear&#10;E) Internal ear

Accepted Answer

The tympanic cavity is located in the middle ear, which is bounded by the tympanic membrane (eardrum) on one side and the bony wall of the inner ear on the other. The middle ear contains three tiny bones (ossicles) that transmit sound vibrations from the eardrum to the inner ear.

Question 8

The ceruminous glands produce a greasy substance known as earwax and are located in the:&#10;A) External auditory canal&#10;B) Internal auditory canal&#10;C) Middle ear&#10;D) Inner ear&#10;E) Tympanic membrane

Accepted Answer

Ceruminous glands are located in the external auditory canal and produce earwax. The other options are not correct as they are not the location of these glands.

Question 9

Jimmy,10 years old,is on the swim team.He practices 4 days a week for 3 hours a day.Jimmy returns from swim practice complaining of ear pain.What is the most likely cause of the pain?&#10;A) Otitis media&#10;B) Otitis externa&#10;C) Cauliflower ear&#10;D) M&#233;ni&#232;re's disease&#10;E) Vertigo

Accepted Answer

Otitis externa, also known as swimmer's ear, is a common cause of ear pain in individuals who swim frequently. It is an infection of the ear canal that can be caused by water trapped in the ear, which creates a moist environment for bacteria to grow. Symptoms include ear pain, itching, redness and discharge.

Question 10

The main purpose of this organ is to collect sound waves and direct them toward the eardrum.This organ is known as the:&#10;A) Middle ear&#10;B) Inner ear&#10;C) Auricle&#10;D) Inner auditory canal&#10;E) Tympanic membrane

Accepted Answer

The organ responsible for collecting sound waves and directing them toward the eardrum is the auricle, also commonly known as the outer ear. The middle ear includes the eardrum and three small bones (ossicles) that transmit sound waves to the inner ear. The inner ear includes the cochlea and various structures responsible for converting sound waves into electrical signals that can be interpreted by the brain. The inner auditory canal is a passageway that connects the inner ear to the brain. The tympanic membrane, also known as the eardrum, is a thin layer of tissue that separates the outer ear from the middle ear and vibrates in response to sound waves.

Question 11

Conductive hearing loss may be caused by:&#10;A) Trauma to the tympanic membrane&#10;B) Streptomycin&#10;C) Antimalarial drugs&#10;D) Tumor of the acoustic nerve&#10;E) Brain injury
