People need salt because it helps to maintain water balance in the body. It also supports the transmission of nerve impulses and the proper functioning of the muscles. Normally, the kidneys regulate the balance of salt in the body by storing it when the levels are low and excreting it in the urine when the levels are too high.Know More

Animals with a larger nerve diameter can better conduct nervous signals throughout the body and thus, possess a faster nerve conduction velocity. The diameter of the nerve indicates the thickness of the myelin sheath, or insulation, around it. The better the insulation, the stronger the nerve signal. In theory, the larger the animal is, the larger its nerve cells. Thus, larger animals would have the fastest nerve conduction velocities.Full Answer >
