Ontology: Ear structure (C0013443)

Definition (MSHCZE) Sluchový a rovnováhu udržující tělesný systém. Skládá se ze 3 částí: VNĚJŠÍHO, STŘEDNÍHO a VNITŘNÍHO ucha. Zvukové vlny jsou přenášeny uchem tak, že vibrace postupují po ZVUKOVÉM NERVU jako nervové signály do CENTRÁLNÍHO NERVOVÉHO SYSTÉMU. Vnitřní ucho obsahuje také vestibulární aparát zajišťující rovnováhu těla nasměrováním signálu k VESTIBULÁRNÍMU NERVU.
Definition (NCI_CDISC) 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. (NCI)

Definition (CSP) organ of hearing and of equilibrium, consisting of the external ear, the middle ear, and the internal ear.
Definition (MSH) 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.

Ontology: Ear ossicle structure (C0013450)

Definition (NCI) The three small bones in the middle ear that transmit acoustic vibrations from the eardrum to the inner ear.
Definition (CSP) small bones of the middle ear; they are articulated to form a chain for the transmission of sound from the tympanic membrane to the oval window.
Definition (MSH) A mobile chain of three small bones (INCUS; MALLEUS; STAPES) in the TYMPANIC CAVITY between the TYMPANIC MEMBRANE and the oval window on the wall of INNER EAR. Sound waves are converted to vibration by the tympanic membrane then transmitted via these ear ossicles to the inner ear.
