The hair cells are arranged in four rows: 

Three rows of outer hair cells (20,000)

One row of inner hair cells (3500)

The processes of the hair cells are bathed in endolymph, whereas their bases are bathed in perilymph, this arrangement is necessary for the normal production of

receptor potentials
