55. which statements are true about the Auditory Function a. Sound waves are funneled by the auricle down the external acoustic meatus, causing the tympanic membrane to vibrate. b. The tympanic membrane vibrations are passed along the auditory ossicles to the oval window of the inner ear. c. Movement of the stapes in the oval window causes the perilymph, vestibular membrane, and endolymph to vibrate, producing movement of the basilar membrane. d.Movement of the basilar membrane causes bending of the stereocilia of inner hair cells in the spiral organ.
Knowing what you know about the anatomy of the eyeball, why do you suppose untreated glaucoma (excess aqueous humor production) causes blindness? Group of answer choices a. The excess aqueous humor compresses the optic nerve b. Intraocular pressure increases and the vitreous body presses against the lens c. The fluid accumulation causes the choroid to separate from the sclera d. The buildup of aqueous humor causes the vitreous body to press against the retina and disrupt its blood supply leading to cell death e. Aqueous humor is not reabsorbed as quickly as it is produced
The inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms.
