scala

 [ska´lah] (L.)
a ladderlike structure, especially any of various passages of the cochlea.
scala me´dia cochlear duct.
scala tym´pani the part of the cochlea below the spiral lamina.
scala vesti´buli the part of the cochlea above the spiral lamina.

sca·la ves·tib·'u·li

[TA]
the division of the spiral canal of the cochlea lying on the apical side of the spiral lamina and vestibular membrane or of scala media.
Synonym(s): vestibular canal

scala vestibuli

(vĕ-stĭb′yə-lī′)
n. pl. scalae vestibulorum (-lôr′əm)
The uppermost of the three divisions of the spiral cavity winding around the modiolus of the cochlea in the inner ear. It is filled with perilymph and receives vibrations from the stapes.

scala vestibuli

See helicotrema.

sca·la ves·tib·u·li

(skā'lă ves-tib'yū-lī) [TA]
The division of the spiral canal of the cochlea lying on the apical side of the spiral lamina and vestibular membrane.
Synonym(s): vestibular canal.

scala vestibuli

A fluid-filled passage in the cochlea running on the outside of the cochlear duct from the oval window in the middle ear to the HELICOTREMA where it communicates with the scala tympani.

scala vestibuli

the upper chamber of the cochlea in mammals, filled with perilymph. It lies between REISSNER'S MEMBRANE and the wall of the bony canal and connects with the SCALA TYMPANI via the helicotrema.

scala

pl. scalae [L.] a ladder-like structure, applied especially to various passages of the cochlea.

scala media
the cochlear duct: a space in the ear between Reissner's membrane and the basilar membrane.
scala tympani
the part of the cochlea below the spiral lamina.
scala vestibuli
the part of the cochlea above the spiral lamina.

For the purpose of this study, a specimen was considered to have severe trauma if any portion of the electrode had deviated from the ST into the scala media or scala vestibuli with associated fracture of the osseous spiral lamina, tearing of the basilar membrane, or dislocation of the spiral ligament.
The stiffness and incidence of insertion trauma resulting in deviation of the electrode array from the ST vertically into the scala media or scala vestibuli are summarized in Table 2.
