Receptor, afferent neuron, integration center, efferent neuron, effector
A substance that is released at axonal endings to propagate a nervous impulse
An action potential: • Is initiated by potassium ion movements • Is essential for nerve impulse propagation • Involves the outflux of negative ions to depolarize the membrane • Involves the influx of negative ions to depolarize the membrane
Put the following in the correct order of what occurs following the threshold potential • Membrane becomes depolarized • Membrane becomes repolarized • Sodium channels open and sodium ions diffuse inward • Potassium channels open and potassium ions diffuse outward while sodium is actively transported out of the cell
Sodium channels open and sodium ions diffuse inward • Membrane becomes depolarized • Potassium channels open and potassium ions diffuse outward while sodium is actively transported out of the cell • Membrane becomes repolarized
The PNS includes: • The brain and spinal cord • Spinal nerves only • Cranial nerves only • Both spinal and cranial nerves

Which of these effectors is NOT directly controlled by the autonomic nervous system? • Abdominal organs • Most glands • Cardiac muscle • Skeletal muscle • Smooth muscle
Which of the following effects is characteristic of the parasympathetic nervous system? • Decrease urine output • Increase metabolic rate • Decreases heart rate • Decreases activity of the digestive system
