scala

 [ska´lah] (L.)
a ladderlike structure, especially any of various passages of the cochlea.

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.

(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
