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.
Video: Dendrites: Definition & Function. Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function. This lesson discusses dendrites, their function, and their importance in neuron activity. The nervous system serves as the manager of the body, since it controls the functions of every other system.
