Explain how the human ear works?
Answers
human ears
The sound waves are gathered by the outerear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move.
Answer:
The anatomy of our hearing or auditory system is extremely complex but can be broadly divided into two parts, one being called ‘peripheral’ and the other ‘central’.
The peripheral hearing system consists of three parts which are the outer ear, the middle ear and the inner ear:
The outer ear consists of the pinna (also called the auricle), ear canal and eardrum.
The middle ear is a small, air-filled space containing three tiny bones called the malleus, incus and stapes but collectively called the ossicles. The malleus connects to the eardrum linking it to the outer ear and the stapes (smallest bone in the body) connects to the inner ear.
The inner ear has both hearing and balance organs. The hearing part of the inner ear and is called the cochlea which comes from the Greek word for ‘snail’ because of its distinctive coiled shape. The cochlea, which contains many thousands of sensory cells (called ‘hair cells’), is connected to the central hearing system by the hearing or auditory nerve. The cochlea is filled with special fluids which are important to the process of hearing.
The central hearing system consists of the auditory nerve and an incredibly complex pathway through the brain stem and onward to the auditory cortex of the brain.
