Which TWO parts does the central nervous system consist of?

• Spinal Cord

• Intestines

• Brain

• Neurons around body

What is the purpose of a neurotransmitter?

• Protect body from bacteria and viruses

• Ensure circulation in the central and peripheral nervous system

• Carry nutrients around the body

• Send chemical signal from one neuron to another

In which direction does the action potential (signal) travel down the neuron?

• Left to right

• Right to left

• Axon

• Myelin Sheath

Name part A

• Dendrite

• Terminal Button

• Axon

• Myelin Sheath

Name part H

• Dendrite

• Terminal Button

• Axon

• Myelin Sheath

What is the purpose of the terminal button (part H)?

• RECEIVE neurotransmitter signals from another neuron's dendrites (part A)

• SEND neurotransmitter signals to another neuron's dendrites (part A)

Name part B

• Cell Body

• Myelin Sheath

• Axon

• Nucleus

Name part C

• Cell Body

• Myelin Sheath

• Axon

• Nucleus

Name part D

• Cell Body

• Myelin Sheath

• Axon

• Nucleus

Name part E

• Dendrite

• Terminal Button

• Axon

• Myelin Sheath
