Nervous System

The Nervous System is divided into two parts called

• The Central Nervous System & The Peripheral Nervous System

• The Central Nervous System & The Paradigm Nervous System

• The Corollary Nervous System & The Paradigm Nervous System

• The Corollary Nervous System & The Peripheral Nervous System

Rapid change in polarity across the axon membrane as the nerve impulse occurs.

• Action potential

• Resting potential

• Threshold

• Firing potential

Normally, the inside of the axon is _______ compared to the outside.

• Positive

• Negative

• Neutral

The two neurons never touch one another but are separated by a tiny gap called_______.

• synaptic cleft

• dentrite

• neurotransmitters

• synaptic integration 

Which is the correct order/sequence of the parts of a neuron in a neural impulse?

• axon, dendrite, cell body, synapse
• dendrite, axon, cell body, synapse
• synapse, axon, dendrite, cell body
• dendrite, cell body, axon, synapse

______ send signals away from neurons whereas ______ receive signals from other neurons.  

• Axons; Dendrites
• Synapses; dendrites
• Dendrites; axons
• Axons; synapses

Area #6 is called the

• neuroglia

• neurilemma

• node of Ranvier

• schwann cell

The part of the neuron that insulates the axon and increases the speed of the neural message within the neuron.

• Synapse
• Dendrite
• Myelin Sheath
• Axon Terminal Button

Which part of the peripheral nervous system deals with activities that we can control?

• somatic

• autonomic

 Which neuron carries nerve impulses from tissues and organs to the spinal cord and brain? 

• sensory neurons
• motor neurons 
• interneurons 
• impulse neurons
