Where in the cochlea are the hair cells, the sensory cells that detect sound?
What is the function of the stria vascularis, the cells that line the scala media or the cochlea duct?
The endolymphatic sac is a blind-ending structure connected to the cochlea and balance organs via the endolymphatic duct (see Figure 2 above). One function of the sac is to secrete endolymph back into the circulatory system. If Julius’ problem is produced by an increase in the pressure of the endolymph, what factors could contribute to an increase in the volume of this fluid?
