Auditory system
The auditory system 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.
The auditory periphery, starting w...

Ear
The ear is the organ that detects sound. It not only receives sound, but also aids in balance and body position. The ear is part of the auditory system.Often the entire organ is considered the ear, th...

Outer ear
The outer ear is the external portion of the ear, which consists of the pinna and external auditory meatus. It gathers sound energy and focuses it on the eardrum (tympanic membrane).
The visible p...

Middle ear
The middle ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear. The mammalian middle ear contains three ossicles, which transfers the vibrations of...

Inner ear
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists o...

Organ of Corti
The organ of Corti (or "spiral organ") is the receptor organ for hearing and is located in the mammalian cochlea. Described as “a masterpiece of cellular micro-architecture,” this highly varied strip...

Hair cell
Hair cells are the sensory receptors of both the auditory system and the vestibular system in all vertebrates. Through mechanotransduction, hair cells detect movement in their environment. In mammals,...

Trapezoid body
The trapezoid body is part of the auditory pathway where some of the axons coming from the cochlear nucleus decussate, or cross over to the other side before traveling on to the superior olivary nucle...
Superior olivary complex
The superior olivary complex (or SOC or superior olive) is a collection of brainstem nuclei that functions in multiple aspects of hearing and is an important component of the ascending and descending ...

Lateral lemniscus
The lateral lemniscus is a tract of axons in the brainstem that carries information about sound from the cochlear nucleus to various brainstem nuclei and ultimately the contralateral inferior collicul...
