Year 9 Science: Parts of a neuron

The dendrite...

• Receives signals from a receptor

• Conducts the signal down the neuron

• Insulates the neuron preventing the signal from leaking out

• Contains neurotransmitters which move across the synapse

The axon...

• Receives signals from a receptor

• Conducts the signal down the neuron

• Insulates the neuron preventing the signal from leaking out

• Contains neurotransmitters which move across the synapse

The myelin sheath...

• Receives signals from a receptor

• Conducts the signal down the neuron

• Insulates the neuron preventing the signal from leaking out

• Contains neurotransmitters which move across the synapse

The axon terminal...

• Receives signals from a receptor

• Conducts the signal down the neuron

• Insulates the neuron preventing the signal from leaking out

• Contains neurotransmitters which move across the synapse
