Identify the type of neuron in the diagram.

• Motor neuron

• Sensory neuron

• Interneuron

The long neural fibre that carries electrical messages from the cell body to the muscles to make them move. This is protected by a layer of fat called a myelin sheath.

• Axon

• Dendrite

• Cell Nucleus

• Node of Ranvier

Within the cell body of a motor neuron, this contains the genetic information for the neuron.

• Axon

• Myelin sheath

• Schwann cell

• Cell nucleus

The layer of fat that protects the axon. This layer is produced by Schwann cells.

• Myelin sheath

• Nodes of Ranvier

• Cell nucleus

• Synapse

The gaps in the Myelin sheath that speed up neural firing along the axon.

• Nodes of Ranvier

• Cell nucleus

• Schwann cell

• Dendrite

The gap between two neurons. This is where neurotransmitters are released to allow neurons to communicate.

• Dendrite

• Axon

• Synapse

• Schwann cell
