Nervous System: Quiz

Acts as the body's control center and coordinates the body's activities.

• Autonomic Nervous System

• Somatic Nervous System

• Peripheral Nervous System

• Central Nervous System

Carries the impulse from the CNS to the effector organ.

• Axon Terminal

• Dendrites

• Sensory Division

• Motor Division

The basic unit of function and structure in the nervous system.

• Neurons

• Axon Terminals

• Axon

• Myelin Sheath

They allow the movement of sodium-potassium ions in and out of the neuron.

• Spike

• Axon Terminals

• Sodium-potassium pump

• Leak channels

The movements of ions in and out of the neurons which creates and electric charge is called?

• Kinetic Potential

• Action Potential

• Resting Potential

• Passive Potential

The phase where the neuron is at rest or not relaying any signal.

• Kinetic Potential

• Passive Potential

• Resting Potential

• Action Potential

The sudden change in charge which resulted to the production of high electric charge.

• Dielectric Polarization

• Depolarization

• Repolarization

• Electrical Synapse

Where the electric charge will drop due to the inactivity of the voltage-gated channels.

• Dielectric Polarization

• Depolarization

• Repolarization

• Electrical Synapse

Involves the use of neurotransmitters to relay the message to another neuron.

• Synaptic Cleft

• Electrical Synapse

• Synaptic Transmission

• Chemical Synapse

Directly relays the action potential to the next neuron.

• Electrical Synapse

• Synaptic Cleft
