Key components of the auditory system

The auditory system is responsible for the sense of hearing. Key components of the auditory system include:

• Outer ear: Captures sound waves from the environment and focuses them on the eardrum
• Middle ear: Amplifies sound vibrations and transmits them to the inner ear
• Inner ear: Transduces sound vibrations and physical motion into neural signals through hair cells, sensory receptors located inside a coiled structure called the cochlea.
  The neural signals then travel to the brain, where they are processed to generate sound perception and localization. Structures in the inner ear are also key components of the vestibular system, which processes sensory  information related to self-motion, head position,  and spatial orientation relative to gravity
