how is pressure transmitted via the ovale window? more celarly, though which fulid in which structure wirst, and then though what sturcture and though waht fluid and sturcte back to the round window?
pressure wave is transmitted to the perilymph within the scala vestibuli of the cochlea.
Since the outer wall of the scala vestibuli is incompressible bone, the pressure wave within is
forced to dissipate through the perilymph either towards the helicotrema and back to the
secondary tympanic membrane at the round window, or, more usually, across the delicate
vestibular membrane and the cochlear duct to the basilar membrane and overlying spiral organ
