  1. Multiple Sclerosis is a process in which the body’s immune system will attach the central nervous system. Alyssa demonstrated a neuron in which the octopus represents the cell body or stroma, whereas the octopus body represents the nucleus of the neuron and the octopus’ legs represent dendrites of the neuron. The axon is found as sweet tart rope and the synapse is shown by clear gummy worms towards the end of the neuron. This demonstrates how the axon is responsible for emitting nerve impulses. As we go down the neuron, oligodendrocytes and myelin are found using twizzler nibs and in between each oligodendrocyte, there is a node of Ranvier found with a gap in twizzler nibs within the sweet tart rope.

    Multiple sclerosis is known to demyelinate axons which is shown on the right neuron as it’s insulation is damaged and scarred. This neuron will have a more difficult time producing signal conduction and communication compared to the neuron on the left. This difficulty can lead to neurological symptoms such as numbness or weakness of limbs, bodily movements, or tremors. In cases that are worsened, there can also be trouble with vision and speech impairment due to improper signaling. So far there are four main types of phenotypes associated with MS known as: clinically isolated syndrome, relapsing-remitting, secondary progressive, and primary progressive. However, there is still a lot of unknown about MS and proper treatment because there is no cure for this disease.
