What is true for mechanism of hearing in humans?

1. Transmission of vibration by stapes to oval window → Waves in lymphs → Ripple in tectorial membrane → Hair cells bend against basilar membrane → Nerve impulse generated in afferent neurons

2. Transmission of vibration by malleus to oval window → Waves in lymphs → Ripple in basilar membrane → Hair cells bend against tectorial membrane → Nerve impulse generated in afferent neurons

3. Transmission of vibration by stapes to oval window → Waves in lymphs → Ripple in basilar membrane → Hair cells bend against tectorial membrane → Nerve impulse generated in afferent neurons

4. Transmission of vibration by stapes to oval window → Waves in lymphs → Ripple in basilar membrane → Hair cells bend against reisnner’s membrane → Nerve impulse generated in efferent neurons
