Elementary biophysics: selected topics elementarybiophy00epst Year: 1963 BM (b) Helicotrema RW Fig. 21. Sketch of the cochlea (a) and a cross section of the cochlea (b). Part (b) shows the separation of the snail-like tube into Vestibular (V), Median or Cochlear (C), and Tympanic (T) canals. The stapes insertion at the end of the vestibular canal is indicated by the dotted line containing the .symbol S, and the round window (RW) at the end of the tympanic canal is similarly indi- cated. BM is the location of the basilar membrane. N is the auditory nerve as it emerges from the cochlea. Par
Elementary biophysics: selected topics elementarybiophy00epst Year: 1963 BM (b) Helicotrema RW Fig. 21. Sketch of the cochlea (a) and a cross section of the cochlea (b). Part (b) shows the separation of the snail-like tube into Vestibular (V), Median or Cochlear (C), and Tympanic (T) canals. The stapes insertion at the end of the vestibular canal is indicated by the dotted line containing the .symbol S, and the round window (RW) at the end of the tympanic canal is similarly indi- cated. BM is the location of the basilar membrane. N is the auditory nerve as it emerges from the cochlea. Part (c) shows a schematized version of the cochlea unwound from its actual snail-like configuration. The basilar membrane divides the two parts of the cochlea; the cochlear canal is omitted for simplicity. The helicotrema allows passage of fluid from one part of the cochlea to the other.
