Tools A B regulation involves the control in life activities nerve control function of nerve cells neurons transmission of impulses dendrites receive impulses cell body receives from the dendrites axon the connection of the cells impulses an electrical and chemical change to the membrane neurontransmitters stimulate the release of chemicals synapses junction b/w adjacent neurons stimulus change in externel and internal environment receptors stimuli are detected by specialized structures responses reactions of an organism to a stimulus effectors generally muscles or glands cyton same thing as the cell body terminal branches receive impulses from axon
