Neuron Physiology

The part of the neuron that receives incoming messages is the

• dendrite

• axon

• cell body

• axon terminal

The part of the neuron that is protected by the myelin sheath is the

• cell body

• dendrites

• axon

• axon terminals

The cell body contains the

• dendrites

• axon terminals

• nucleus and many organelles

• myelin sheath

An electrical impulse within a single neuron is called a

• synapse

• membrane potential

• action potential

• cell body

What maintains the resting membrane potential in a neuron?

• sodium-potassium pumps

• sodium channels

• potassium channels

• gravity
