> Facilitated Transport: Accelerated Diffusion (Figure 10.20)

> > Pore Facilitated Transport (Figure 10.20, Figure 10.21, Figure 10.22)

Excitable Membranes, Action Potentials, and Neurotransmission (Figure 10.29)

> The Resting Potential (Equations 10.8, 10.9, 10.10, Figure 10.30)

> The Action Potential (Figure 10.31, Figure 10.32, Figure 10.33

> > 1. The action potential does not appreciably decrease with distance transmitted.
> > 2. The action potential is an all-or-none phenomenon.
> > 3. After an impulse has passed, the region of axon immediately behind it is unable to transmit another impulse for a period of some milliseconds because of the refractory period.
