the function of dendrons is that the dendron has dendrite on the end which receive impulses from receptor cells or other neurones which are then moved along the dendron to the axon.
To do this, the dendritic cells capture the antigens from invading bodies, which they process and then present on their cell surface and presented, along with the necessary accessory or co-stimulation molecules. Dendritic cells also contribute to the function of B cells and help maintain their immune memory.
