| auditory nerve | <anatomy, neurology> Cranial nerve VIII is responsible for the sense of hearing and balance (body position sense). Lesions of the eighth nerve can result in deafness, tinnitus, dizziness, vertigo and vomiting. (27 Sep 1997) |
|---|---|
| auditory nucleus | vestibulocochlear nuclei |
| auditory oculogyric reflex | Rotation of the eyes toward the source of a sudden sound. (05 Mar 2000) |
| auditory organ | Archaic term for gustatory organ. (05 Mar 2000) |
| auditory ossicles | The 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. Synonym: ossicula auditus, ear bones, ossicular chain. (05 Mar 2000) |
| auditory pathway | Neural paths and connections within the central nervous system, beginning at the organ of Corti's hair cells, continuing along the eighth nerve, and terminating at the auditory cortex. (05 Mar 2000) |
| auditory perception | The process whereby auditory stimuli are selected, organised and interpreted by the organism; includes speech discrimination. (12 Dec 1998) |
| auditory perceptual disorders | Disorders of auditory perception manifesting as difficulties with auditory memory, speech perception and sound localization. Lesions are usually in the temporal lobe. (12 Dec 1998) |
| auditory pits | Paired depressions, one on either side of the head of the embryo, marking the location of the future auditory vesicles. Synonym: otic pits. (05 Mar 2000) |
| auditory placodes | Paired ectodermal placode's that sink below the general level of the superficial ectoderm to form the auditory vesicles. Synonym: otic placodes. (05 Mar 2000) |
| auditory process | The roughened edge of the tympanic plate giving attachment to the cartilaginous portion of the external acoustic meatus. (05 Mar 2000) |
| auditory receptor cells | Columnar cell's in the epithelium of the organ of Corti, having hairs (stereocilia) on their apical ends. See: Corti's cells. (05 Mar 2000) |

| auditory striae | Slender fascicles of fibres extending transversally below the ependymal floor of the ventricle from the median sulcus to enter the inferior cerebellar peduncle. They arise from the arcuate nuclei on the ventral surface of the medullary pyramid. Synonym: striae medullares ventriculi quarti, acoustic striae, auditory striae, Bergmann's cords, medullary teniae, teniae acusticae. (05 Mar 2000) |
| auditory strings | Bundles of parallel filaments in the zona pectinata of the lamina basilaris of the cochlea; the length of the string's varies from 64 um in the basal coil to 480 um in the apex. (05 Mar 2000) |
