Question

Sort the order by which the sound waves travel through the ear for interpretation.

• A. Brain
• B. Cochlea
• C. Ear ossicles
• D. Ear drum
• E. Pinna

Answer 1

The pinna collects sound waves from outside and sends it to the ear drum or tympanic membrane. The ossicular chain behind the ear drum amplifies the incoming vibrations and sends it via the oval window to the inner ear. The inner ear contains a fluid filled cochlea that houses the organ of Corti. It interprets the vibrations and converts them into nerve impulses. These nerve impulses are sent to the brain through cochlear nerve for interpretation.
