Answer:

Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.

ikadub [295]
<span>Georgio instantly feels pain due to the message carried to his brain by </span>myelinated axons.  The message of the ache is carried by unmyelinated axons.
The myelinated axon is highly "insulated" axon that r<span>eceives input and transmit impulse quickly.</span>
The purpose of the naked axon with larger dendritic field which is called unmyelinated axon is to receive as much input as possible.
