What's the difference between nervous system and endocrine?The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. … The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue. Responses to endocrine system stimulation are typically slow but long lasting.
