Hair cells in the vertebrate ear are responsible for transducing sound pressure waves.When do ion channels in the hair cell membrane open?

Question

Quizplus · Accepted Answer

Ion channels in the hair cell membrane open when the membrane is mechanically distorted, which occurs when sound pressure waves cause the stereocilia on the hair cell to move. This movement leads to the opening of ion channels, which triggers the release of neurotransmitters and ultimately results in the transmission of auditory signals to the brain. Options A and B refer to other types of receptors, while option C refers to the mechanism of action of neurons, not hair cells. Option E is also incorrect, as hair cells do not receive action potentials but generate graded potentials.
