ACLIOr potential +40 Falled Threshold -55 initiations Resting state -70 Stimulus 1 Refractory period 3. 5. 2 Time (ms) Which of the following are true about the propagation of an action potential? O Action potential is triggered by the opening of voltage gated potassium channels Once threshold potential is reached, the neuron always depolarizes O The refractory period prevents propagation back to the point of initiation of the action potential Once initiated, the action potential propagates in an all or nothing fashion Voltage (mV) Depolarization Repolarization

The nervous system is the network of control and coordination in the body. The stimulus received by the body are responded by the brain.
This receiving and return of signals and responses takes place through the nerve cells. The nerve cells are also known as neurons.
