1 Nerve Tissue Diseases: Rabies1 On his way to work, Elmo was bitten by a dog. Within 2 months, Elmo began having mild convulsions and showed rage and signs of confusion. A few weeks later, he began to foam at the mouth when he saw water. Elmo was taken to the hospital immediately to receive treatment against rabies. The doctor explained that when the infected dog bit Elmo, the rabies virus in the dog’s saliva entered Elmo’s body and traveled along the sensory nerves to the spinal cord and from the spinal cord to the brain. Elmo began showing signs of confusion and rage when the virus reached his brain. He could not swallow water or food because in absence of appropriate nerve impulses from the brain, the muscles in his throat were paralyzed. You can help Elmo by completing the following tasks: A. Follow the path of the virus from the skin on Elmo’s leg to the spinal cordand the brain by locating the structures below.  B. Draw and label the three connective tissue layers that cover and protect the spinal nerves.
