The Structure of a Neuron Essential Questions

Why do athletes use sports drinks? Sports drinks replenish your electrolytes after and during exercise. Those sports drinks contain electrolytes such as chloride, sodium, and potassium. These electrolytes are lost from the body through sweat and potassium and sodium play a huge role in muscle contractions. The sodium potassium pump is a significant step in a muscle correction because it controls the ions traveling on each side of the cell membrane. When those ions are lost through sweat the sports drinks can replenish them thus continuing the ability to produce strenuous exercise with muscle contractions. The longest nerve in the body is the sciatic nerve, and it runs from the bottom of the spinal cord to the big toe on each foot. That is a length of approximately three feet for one neuron!
