Question
When you move your head from left to right your vestibular system ‘tells’ you what you were doing. How does it work?
An unusually high concentration of K+ in the fluid of the canal makes the entire sensory cell extremely sensitive to motion
Moving your head causes the hair cells to experience centrifugal force which causes small dense particles in the cell’s cytoplasm to move to the outer edge of the cell. As the particles touch receptor proteins, signals are sent to a nearby sensory axon
Fluid in one of the semicircular canals moves relative to your head and causes hair cells to release signal molecules onto a sensory neuron’s axon tip
A receptor potential in one receptor cell is transmitted to other receptor cells and finally to a sensory axon

4.A receptor potential in one receptor cell is transmitted to other receptor cells and finally to a sensory axon
Explanation / Answer
correct answer is 2- Moving your head causes the hair cells to experience centrifugal force which causes small dense particles in the cell’s cytoplasm to move to the outer edge of the cell. As the particles touch receptor proteins, signals are sent to a nearby sensory axon. it is passive movement occur in horizontal axis.
