which statements are true about the Auditory Structures and Functions
a. The external ear consists of the auricle and external acoustic meatus.
b. The middle ear connects the external and inner ears. The tympanic membrane is stretched across the external acoustic meatus.
c. The malleus, incus, and stapes connect the tympanic membrane to the oval window of the outer ear.
d. The auditory tube connects the middle ear to the pharynx and functions to equalize pressure.
which statements are true about the Auditory Structures and their Functions
a. The middle ear is connected to the mastoid air cells.
b. The inner ear has three parts: the semicircular canals; the vestibule, which contains the utricle and the saccule; and the cochlea.
c. The cochlea is a circular-shaped canal within the temporal bone.
d. The cochlea is divided into two compartments by the vestibular and basilar membranes. The scala vestibuli and scala tympani contain perilymph. The cochlear duct contains endolymph and the spiral organ (organ of Corti).
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.
