, 07:59, 25 August 2011→Neuronal Transport Mechanisms
Neurons are often quite large when compared to other cell types within the body and therefore the transport of molecules, organelles and other elements important to the cell becomes more difficult and equally more important. Neurons have developed a number of mechanisms to transport material throughout the cell.

===Anterograde Transport===
===Anterograde Transport===
Anterograde transport facilitates the movement of substances in the direction of the cell body to the axon. This type of neuronal transport has been covered in detail within the PNS Structure and Anatomy page, please click [[PNS_Structure_-_Anatomy_%26_Physiology#Anterograde_Transport|here]].
===Retrograde Transport===
Retrograde transport is the opposite of anterograde in that it returns materials from the axon terminal to the cell body, either for degradation or restoration and reuse. This type of neuronal transport has been covered in detail within the PNS Structure and Anatomy page, please click [[PNS_Structure_-_Anatomy_%26_Physiology#Retrograde_Transport|here]].
==Neuron Blood Supply==
The blood supply to nerves is called the '''vasa nervorum'''. The blood supply to neurons has been covered in detail within the PNS Structure and Anatomy, please click [[PNS_Structure_-_Anatomy_%26_Physiology#Blood_Supply|here]].
