Fantastic animated tutorials from McGraw Hill Education – the Nerve Impulse, Action Potential propagation in unmyelinated axons, Voltage-gated channels &  the action potential, Sodium-Potassium exchange pump,  how it works & the sodium channel involved in nerve transmission. Also transmission across a synapse

From Sinauer Associates we have an animated, narrated tutorial on Reflex Arcs which also includes a quiz and here are animated, narrated tutorials on the synapse and action potentials.
