  1. Neurons

  2. Neurons The cells that carry the messages throughout the nervous system

  3. Parts of a Neuron - Dendrites Branched projections of a neuron that receives signals from other neurons. Sends signals to the cell body.

  4. Parts of a Neuron - Cell Body The cell body contains the nucleus and other organelles. Dendrites branch off of the cell body.

  5. Parts of a Neuron - Axon The axon is a long, projection of the neuron that conducts the electrical impulse away from the cell body

  6. Parts of a Neuron - Myelin Sheath Myelin forms a layer around the axon and functions to increase the speed of electrical impulses along axon

  7. Parts of a Neuron - Schwann Cells Schwann cells form myelin, which help conduct nerve impulses along the axon

  8. Parts of a Neuron - Nodes of Ranvier Nodes of Ranvier are gaps between the myelin sheaths. Electrical impulses jump from node to node, which helps to increase the speed of conduction.

  9. Parts of a Neuron - Axon Terminals Axon terminals are the end branches of a neuron.

  10. Synapse A structure at the end of the axon terminal that releases a neurotransmitter to an adjacent neuron.
