Your Answer:tympanic membrane
One of the names given to the cartilaginous funnel attached to the side of the head.
The ossicular hammer.
The middle ear is connected to the nasopharynx via this.
Your Answer:eustachian tube

The other name given to the cartilaginous funnel attached to the side of the head.
Structures responsible for equilibrium and balance.
Correct Answer:semicircular canals
An ear, nose, and throat practitioner.
An S-shaped canal approximately 1 cm in length.
Your Answer:external acoustic meatus
The structure containing the round or oval window.
Testing if there is a defect in any part of the hearing apparatus using an acoustic stimulus is called _____.
Your Answer:I. air conduction
A test that tests only the inner ear, 8th cranial nerve, and central pathways using a tuning fork is called _____.
Your Answer:J. bone conduction
This type of tuning fork is placed on the midline of the head and the patient indicates in which ear they can hear the tone.
Your Answer:B. Weber tuning fork
The tines of a vibrating tuning fork are held near the pinna and then the stem of the fork is placed in contact with the mastoid process.
Your Answer:F. Rinne tuning fork
Used to quantitate hearing loss.
Your Answer:A. audiometer
Hearing loss is measured in _____.
Your Answer:C. decibels
The intensity at which speech is recognized.
Your Answer:H. spondee threshold
Measuring the effectiveness of the middle ear by placing a sound source into the external auditory canal and measuring the energy that passes through the middle ear.
Your Answer:G. tympanometry
The means used to determine the underlying disease processes associated with ear symptoms other than hearing loss.
Your Answer:E. otoscopy
Assists in evaluating the mobility of the tympanic membrane by otoscopy.
Your Answer:D. Valsalva maneuver
. air conduction
1. acoustic neuroma or neurinoma Enlarging, benign tumor usually within the internal auditory canal. Also called acoustic schwannoma.
2. anosmia Loss of sense of smell.
3. ceruminoma A tumor of the ceruminous glands.
4. cholesteatoma A nodular growth of squamous epithelium derived from the cells in the external ear, but extending into the middle ear. This is a complication of otitis media and appears as a pearly white, shiny, formed, brittle mass.
5. labyrinthitis Inflammation of the labyrinth (the inner ear).
6. mastoiditis Inflammation of the mastoid air cells.
7. Meniere disease A disorder characterized by recurrent vertigo when lying down, sensory hearing loss, and tinnitus. It is associated with a dilation of the membranous labyrinth.
8. myringitis Inflammation of the tympanic membrane.
9. otitis externa Inflammation or infection of the external canal or the auricle. Swimmer's ear is one form of otitis externa.
Enlarging, benign tumor usually within the internal auditory canal. Also called acoustic schwannoma.
otitis media Inflammation of the middle ear marked by pain, fever, abnormal hearing, hearing loss, tinnitus, and vertigo. This is the most common "ear infection." There are different types, such as acute otitis media, which is a bacterial infection in the middle ear, usually secondary to an upper respiratory infection; chronic otitis media, which is a permanent perforation of the tympanic membrane; and serous otitis media, which is an effusion in the middle ear and which arises from incomplete resolution of an acute otitis media or obstruction of the eustachian tube. A common surgical procedure to aid in the reduction of infectious liquid being trapped behind the tympanic membrane in patients with chronic suppurative otitis media is myringotomy with tubes (making a hole in the tympanic membrane and placing a drainage tube through it).
2. otosclerosis A condition of a bony labyrinth in which there is spongy bone formation in front of and behind the stapes, resulting in conductive hearing loss.
3. perforation A hole made through a part or substance. A perforated tympanic membrane is a common ear problem and most often heals without the need for surgical repair.
4. pharyngitis Inflammation of the pharynx (a sore throat).
5. presbycusis The sensorineural hearing loss which occurs as a part of normal aging.
6. rhinitis Seen most frequently in upper respiratory tract infection; this inflammation of the mucous membrane of the nose is characterized by edema and dilation of the nasal mucous membrane, nasal discharge, and nasal obstruction.
7. schwannoma An acoustic neurinoma; an enlarging, benign tumor usually within the internal auditory canal which arises from cells of the 8th cranial nerve.
8. sinusitis Inflammation of the sinuses, usually the paranasal sinuses, which may be purulent or nonpurulent. Types are named for the sinuses involved.
9. vestibular neuronitis A benign disorder which is characterized by the sudden onset of severe vertigo which is persistent at first and then becomes paroxysmal.

Loss of smell.
Plugging your nose, closing your mouth and blowing.
Your Answer:Valsalva maneuver
The unit by which sound is measured.
Disease characterized by vertigo when prostrate, hearing loss, and tinnitus.
Your Answer:Meniere disease
Discharge from the ear.
The most common ear infection.
Your Answer:otitis media
The intensity at which speech is recognized.
Your Answer:Spondee threshold

Inflammation of the tympanic membrane.
A benign tumor that arises from the cells of the 8th cranial nerve.
The ability to recognize and repeat one-syllable words.
A tumor of the glands that produce cerumen.
Hearing loss of the external canal.
Spongy bone formation behind and in front of the stapes.
Nasal discharge and obstruction.

Correct Answer:vestibular neuronitis
Hearing loss of either the inner ear or cranial nerve.
A type of tuning fork test.
A nodular growth of squamous epithelium, a complication of otitis media.
Inflammation of the inner ear.
Your Answer:otitis externa
