When the action potential reaches the terminal bouton, voltage-gated _______________________ channels are stimulated to open.

Cholinergic β receptors can be blocked with a β blocker to reduce blood pressure and slow heart rate.

At the peak of the action potential when the cell begins to repolarize, the sodium channels are in the ____________________________ state.

When the concentration of a solute no longer affects the rate of transport across the membrane, transport is considered to be at the _______________________________________.

This disease is a result of a build up of amyloid plaques in the brain

Sodium channels can be stimulated again when they are in the inactivated state.

The gap junction is formed by protein called _____________________________.

The tendency toward a stable equilibrium maintained by physiological processes is called the internal millieu.

All of the following are forms of transport into the cell except

One of the primary components of the plasma membrane is the _____________________, which have a hydrophilic head and a hydrophobic tail.
