Answer:
Similarity
Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.
Difference
1. nervous system uses electrical impulses (neural)for signaling while endocrine system uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
