The ear is divided into three parts:
Outer Ear – Includes the pinna and the external auditory canal, which leads to the eardrum.
Middle Ear – Contains three tiny bones (ossicles).
Inner Ear – Houses the cochlea and the balance organ.
Sounds in our environment create sound waves. These waves travel to the pinna and through the external auditory canal to the eardrum. The eardrum vibrates, causing the ossicles to move. These vibrations are transmitted to the cochlea in the inner ear.
Inside the cochlea are sensory cells known as "hair cells." These hair cells move within the fluid and convert the vibrations into electrical signals, which are sent to the brain via the auditory nerve. Finally, the brain processes this information in its auditory centers, allowing us to perceive and interpret sounds.
