NGSS.MS-LS1-2

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

These carry signals from tissues and organs to the brain and spinal cord

• Sensory Neurons
• Motor Neurons
• Efferent Neurons
• Glial Cells

These connect Sensory and Motor Neurons to each other and are located in the brain and spinal cord

• Sensory Neurons
• Motor Neurons
• Interneurons
• Afferent Neurons

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

also known as motor nerves...

• dendrites
• afferent nerves
• bones
• efferent nerves
