What is true of axons?

Axons are long, slender projections of neurons that transmit electrical impulses away from the cell body to other neurons, muscles, or glands. They are essential for the propagation of action potentials and are often insulated by a myelin sheath, which enhances the speed of signal transmission. Axons can vary in length and diameter, influencing their conduction velocity, and they play a crucial role in neural communication and overall nervous system function.
