- Receptor cells that are neurons with sensory dendrites are faster than receptor cells that are separate from neurons. Why is that, and why might that be important in, for example, the sense of touch versus vision?arrow_forwardLinear acceleration, such as the forward movement of being in a car, will result in Depolarization or hyperpolarization of hair cells within the utricle and saccule. Tonic release of neurotransmitters in the cochlea. Depolarization of hair cells within the semicircular canals. two of the above are correctarrow_forwardWhat specific information do hair cells convey? How would your brain interpret a low frequency of action potentials vs a high frequency of action potentials generated by a specific hair cell?arrow_forward

The influx of which ion usually causes this? Which ions cause depolarization in hair cells? Why does K+ move into these cells, rather than out?arrow_forwardBased on the same attached figure as above (Figure 10.9 in your textbook), what kind of channel permits K+ to pass through the apical-end membrane in hair cells of the ear?

Which option best explains this phenomenon? Hair cells release a small amount of neurotransmitter at rest. The continued depolarization of hair cells within the utricle and saccule. Fluid continues to circulate through the semicircular canals. Two of the above.arrow_forwardDescribe what a graph of action potential amplitude vs stimulus intensity for a frog sciatic nerve would look like.
