He made many drawings of the different cells, many of which are still used today. This discovery is important because it illustrated the uniqueness of the nerve cells and has lead to more research into the complex way the nerve cells communicate and transmit information to one another. Afferent means that information is being brought into a structure, while efferent means that information is being carried away from a structure. An axon can be both. While an axon is afferent to one structure, it might be efferent to another, much the same way a car leaving one city enters another.
Efferent means output, or moving away from the reference point.
Afferent means input, or moving towards the reference point. An axon could be either afferent or efferent depending on the point of reference. Explain the mechanism of how it functions. Since the concentration of Sodium is higher outside the cell, the gradient would allow movement of sodium inside the cell, where the concentration of sodium is less concentrated. Explain the mechanism of how it functions.
