• A sensory organ that contains auditory and vestibular apparatuses.
  CDISC Terminology
  Clinical Data Interchange Standards Consortium (CDISC), 2021
• A sense organ needed for the detection of sound and for establishing balance. The outer ear consists of the auricle, the ear canal as well as the tympanic membrane. The middle ear is made up of an air-filled cavity behind the tympanic membrane that contains the ossicles (malleus, incus and stapes). The inner ear is made up of the cochlea needed for hearing and the vestibular apparatus required for balance.

• Subdivision of auriculotemporal part of head which has external, middle and intenal regional parts. Examples: There are only two ears.

• The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.

• The ear, which is the organ of hearing and balance, consists of the outer, middle, and inner ear. The outer, middle, and inner ear function together to convert sound waves into nerve impulses that travel to the brain, where they are perceived as sound.

• The anatomy of the ear is composed of the following parts: External ear (auricle) Middle ear (tympanic): Malleus, incus, and stapes (see the image below) Inner ear (labyrinthine): Semicircular canals, vestibule, cochlea (see the image below) The ear is a multifaceted organ that connects the cen...

• Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction (or the conversion of sound waves into electrochemical impulses) and maintains the sense of balance (equilibrium). The human ear, like that of other mammals, contains sense organs that serve two quite...
