Auditory system
Auditory System
The Auditory System (pronounced: aw-dit-or-ee sis-tem) is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
Etymology
The term "auditory" comes from the Latin word "audire", which means "to hear", and "system" comes from the Latin word "systema", which means "an organized whole".
Structure
The auditory system is divided into two main parts: the Peripheral Auditory System and the Central Auditory System.
Peripheral Auditory System
The peripheral auditory system consists of the structures of the ear, which are the Outer Ear, the Middle Ear, and the Inner Ear.
Outer Ear
The outer ear includes the Pinna and the Ear Canal.
Middle Ear
The middle ear contains the Tympanic Membrane and the Ossicles.
Inner Ear
The inner ear is where the Cochlea and the Vestibular System are located.
Central Auditory System
The central auditory system is the part of the auditory system that is located in the brain. It includes the Auditory Nerve, the Cochlear Nucleus, the Superior Olivary Complex, the Lateral Lemniscus, the Inferior Colliculus, the Medial Geniculate Body, and the Auditory Cortex.
Function
The auditory system is responsible for converting sound waves into electrical signals, which can be interpreted by the brain. This process involves several steps, including sound wave capture, amplification, conversion, and interpretation.
