QUESTION:

Problem 12PE

The speed of propagation of the action potential (an electrical signal) in a nerve cell depends (inversely) on the diameter of the axon (nerve fiber). If the nerve cell connecting the spinal cord to your feet is 1.1 m long, and the nerve impulse speed is 18 m/s, how long does it take for the nerve signal to travel this distance?

QUESTION:

Problem 12PE

The speed of propagation of the action potential (an electrical signal) in a nerve cell depends (inversely) on the diameter of the axon (nerve fiber). If the nerve cell connecting the spinal cord to your feet is 1.1 m long, and the nerve impulse speed is 18 m/s, how long does it take for the nerve signal to travel this distance?

ANSWER:

Solution to 12PE

Step 1 of 2

We need to find the time it takes for the nerve impulse to travel 1.1m distance from the feet to spinal cord. The nerve impulse speed is given as 18m/s.
