MeSH Heading: Ear, Inner
Tree Number(s): A09.246.300
Unique ID: D007758
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D007758
Annotation: /inj: pressure-induced injuries = EAR, INNER / inj (IM) + BAROTRAUMA (IM), noise-induced injuries = HEARING LOSS, NOISE-INDUCED; inflammation = LABYRINTHITIS; neoplasms = LABYRINTH DISEASES (IM) + EAR NEOPLASMS (IM) + histological type of neoplasm (IM)
Scope Note: The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.
