Summary Introduction
Introduction:
The cochlea is the part of the inner ear that is involved in the hearing process. In humans, it makes 2 turns in the bony labyrinth as a spiral-shaped cavity. Organ of Corti is the core component of the cochlea. The waves are propagated from the base to the apex in the spiral cavity of the cochlea.

which statements is false 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).

- Ototoxic 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_forwardHearing in brain is associated with: A. Frontal lobe B.
