A Systemic Approach. Prentice Hall, New Jersey. Nerve Tissue Diseases: Tetanus1 While visiting his aunt that lives on a horse farm, Milo fell and injured his knee. His aunt cleaned the wound and covered the area with bandage. A week later, Milo was taken to the hospital because he could not open his jaws or swallow food. The doctor explained that a bacteria called tetanus bacillus that lives in animals’ intestines had entered the wound on Milo’s knee. The bacterium produced a strong toxin that stimulated Milo’s motor nerves innervating his jaws causing severe spasm of the muscles. Help Milo understand his condition by completing the following tasks: A. Draw and label the parts of amotor neuron. B.
