Cells of the Nervous System

Practice: Guillain-Barre Syndrome is a demyelinating disease caused by sudden-onset immune system attack on the axons (and their myelin sheathes) of neurons in the periphery. How will the function of neurons be affected in patients with Guillain-Barre Syndrome?

Practice: A neuron has its cell body in the spinal cord and sends an axon out into the periphery to synapse onto a skeletal muscle fiber. When this neuron is activated, the skeletal muscle fiber becomes activated, and contracts. Which of the following accurately describes this neuron?
