Which of the following is NOT a common characteristic shared by both the nervous and endocrine systems?

Explanation

Both the nervous and endocrine systems produce and release chemical messengers into extracellular spaces and play roles in homeostasis. However, the nervous system typically acts quickly with short-lived effects, whereas the endocrine system tends to have slower but more prolonged actions. Therefore, having slow and prolonged effects is not a similarity shared by both systems.
