Question 1

Describe the structure of a myelinated motor neurone

Answer 1

• dendrite =branches coming out of neurone
• Cell body = part containing the dendrites
• Axon = long tail
• Myelin sheath = made of Schwann cells creating a layer of insulation
• Node = gaps between myelin sheath
• Axon terminal = end branches of a neuron
Direction of nerve impulses is Dendrite => axon terminal
