Neurons & Neural Communication

A nerve cell that is the basic working unit of the brain and nervous system which processes and transmits information

• axon
• neuron
• dendrite
• neurotransmitter

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

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

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

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

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