BIO: Nervous System

The long, fiber like part of a neuron which the cell sends information to receiving neurons

• axon 
• dendrite
• axon terminal
• gene

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

This part of the neuron stores then releases neurotransmitters into the synapse.

• Axon 
• Dendrite
• Myelin Sheath
• Axon Terminal

What is the purpose of the myelin sheath on the axon?

• To maintain temperature
• To improve conductivity
• To protect the axon
• To release neurotransmitters

What is NOT part of the peripheral nervous system (PNS)?

• axons
• sensory receptors
• spinal cord
• motor neurons

part of a neuron that receives information from other neurons

• axon
• dendrites
• myelin sheath
• synapse

Location at which a neuron can transfer an impulse to another cell with the use of neurotransmitters is called __________.

• myelin sheath
• axon
• threshold
• synapse
