A. Nerve cells, such as the one shown in the diagram to right, transmit electrical signals between sensory receptors and the brain, and then to the muscles. A nerve cell, consists of a cell body with dendrites where the signals come in, and a long axon at the other end where signals are sent out. The axon has a membrane with a 90 mV potential difference across an 8.0 nm thick membrane. The axon is like a long tube, with a radius of 5 µm and a length of 1 m. The dielectric constant of the membrane is 7. Given the radius of the axon and the thickness of the membrane, what sort of capacitor can you treat the axon membrane as being equivalent to? dendrite Cell body i.

To measure signal propagation in a nerve in the arm, the nerve is triggered near the armpit. The peak of the action potential is measured at the elbow and then, 4.0 ms later, 24 cm away from the elbow at the wrist.a. What is the speed of propagation along this nerve?b. A determination of the speed made by measuring the time between the application of a stimulus at the armpit and the peak of an action potential at the elbow or the wrist would be inaccurate. Explain the problem with this approach, and why the noted technique is preferable.
