Which abnormality could give rise to sensorineural deafness?
A) rupture of the tympanic membrane
B) disease or injury in the organ of Corti
C) restriction of ossicular movement because of adhesions between the bones
D) damage to the occipital lobes of the cortex

Question

Quizplus · Accepted Answer

Sensorineural deafness refers to hearing loss caused by damage to the sensory cells (hair cells) or nerves in the inner ear (cochlea) or the pathways that transmit sound from the inner ear to the brain. Therefore, any abnormalities that affect the organ of Corti, which is responsible for converting sound vibrations into neural signals, can lead to sensorineural deafness. Rupture of the tympanic membrane (A) would cause conductive deafness, as it would interfere with sound transmission to the inner ear. Restriction of ossicular movement because of adhesions between the bones (C) would also cause conductive deafness by interfering with sound amplification in the middle ear. Damage to the occipital lobes of the cortex (D) would affect visual processing, not auditory processing.
