Hair bundles within the vestibular system transduce vibratio

Hair bundles within the vestibular system transduce vibration to electrical signals by G protein coupled receptors proteins K+ current through mechanoreceptors connected to tip-link cGMP-gated Na+ channels CAMP second messenger system Save Question 35 high situations? which receptor is primarily used during light which receptor is primarily used during high light situations? Vitamin A

Solution

Ans b is correct

The deflection of the hair-cell stereocilia opens gated ion channels that permits any small, positively charged ions (primarily potassium and calcium) to enter the cell. Unlike many other electrically active cells, the hair cell itself does not fire an action potential. Instead, the influx of positive ions from the endolymph in the scala media depolarizes the cell, resulting in a receptor potential.
