Question93:-Which of the following statement is/are false about endocochlear
potential ?

i. An electrical potential of about + 40 millivolts exist all the time between
endolymph and perilymph.

ii.Positivity is inside the scala media and negativity is outside.

iii. It is generated by continual secretion of positive potassium ions into the outiside
of scala media by the striae vascularis.

iv. The importance of the endocochlear potentail is that the tops of the hair cells
project through the reticular lamina and are bathed by the endolymph of scala
media, whereas perilymph bathes the lower bodies of hair cells.
