Watch this video (http://openstaxcollege.org/l/graymatter) to learn about the gray matter of the spinal cord that receives input from fibers of the dorsal (posterior) root and sends information out through the fibers of the ventral (anterior) root. As discussed in this video, these connections represent the interactions of the CNS with peripheral structures for both sensory and motor functions. The cervical and lumbar spinal cords have enlargements as a result of larger populations of neurons. What are these enlargements responsible for?

- "My Leg is on Fire": A Case Study on Spinal and Peripheral Nerve Anatomy Sarah Mitchell is a 68-year-old female who is normally healthy. However, about five days ago she began to feel very fatigued and started to experience a burning and tingling sensation on her right thigh. You ask to see the area and upon visual inspection you notice 3–4 small, red, swollen areas with vesicles on the posterior aspect of her right thigh. She describes the pain to you, saying “it feels like the back of my leg is on fire and it hurts so bad.” She denies being exposed to any excessive heat sources, any changes in her diet, and any changes in the type of body soap, lotion, or laundry detergent she is using. All other physical findings are within normal limits, but her oral temperature is 100.6˚F. She complains about being under a lot of stress for the past three months because she has been helping take care of her husband, who is in the end stages of Alzheimer’s disease. She has no known drug allergies,…arrow_forward"My Leg is on Fire": A Case Study on Spinal and Peripheral Nerve Anatomy Sarah Mitchell is a 68-year-old female who is normally healthy.
