Question

What mechanism described below could be a cause of partial hearing loss?

1) increased calcium in the endolymph
2) increased expression of hair cell stereocilia
3) increased potassium in the endolymph
4) increased intracellular sodium (hair cell)
5) increased intracellular potassium (hair cell)

Answer 1

Increased potassium in the endolymph can cause partial hearing loss.

Step-by-step explanation:

Partial hearing loss can be caused by an increased level of potassium in the endolymph. The endolymph is the fluid found within the cochlea, and an imbalance in its potassium concentration can disrupt auditory signals. This can lead to a reduction in hearing ability.
