Question

Which of the following correctly traces the energy of sound waves into the ear:
A. Auditory canal-eardrum-ear bones-cochlea
B. Eardrum-auditory canal-cochlea-ear bones
C. Auditory canal-ear bones-eardrum-cochlea
D. Eardrum-auditory canal-ear bones-cochlea

Answer 1

Hint: Our hearing system, which is actually the mechanism of our ears, is extremely complicated. It involves gathering sound waves from outside sources and sending them to nerve tissue, which then transmits them to the brain for interpretation.

Complete Step by Step Answer:
The pinna, the sole component of the ear that is visible to us from the outside, is responsible for collecting the sound, which is nothing more than a type of wave. The eardrum receives it and acts as a vibrating receptacle for the outer wave. Even the smallest sound can be picked up by it.

The middle ear's malleus, incus, and stapes chain of tiny bones are moved by the eardrum movements, which then transmit the sound vibrations to the cochlea. This occurs as a result of the stapes, the final bone in this chain, sitting in a window covered in membrane in the bony wall that divides the middle ear from the cochlea of the inner ear. The cochlea's fluids travel in a wave-like fashion as the stapes vibrates, triggering the tiny hair cells.

Before reaching the auditory cortex, the brain's hearing centres, these nerve impulses travel a convoluted course. Here, the streams of nerve impulses are transformed into audible speech.

Hence, the correct option is A. Auditory canal-eardrum-ear bones-cochlea

Note: It is a quick procedure that travels from the outside to the brain in a tiny fraction of a second. But in the end, only the brain is able to perceive it and give it meaning. Partial or complete hearing effects are both possible. Partial or complete hearing effects are both possible. This could be the result of a congenital disorder, an accident, a handicap, or biochemical factors. Conductive hearing loss refers to hearing loss that is brought on by damage to the outer or middle ear.
