Name one of the two chemical components that make up the hydrophilic head of the plasma membrane component in the previous question: _____________________________________.

The Ca+ Pump is an example of 

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.
