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.
Dendritic cells (DCs) are antigen-presenting cells (also known as accessory cells) of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system.t certain development stages they grow branched projections, the dendrites that give the cell its name (Î´Î­Î½Î´ÏÎ¿Î½ or dendron dÃ©ndron Being greek for). Tree while similar in, appearance these are structures distinct from the dendrites of. neurons
