The nervous system transmits information from the stimuli rapidly by nerve impulses. This passing of information involves very short-range signals. However, they are short-lasting, so they cannot communicate directly to target cells (i.e., liver cells to release glucose). Consequently, the nervous system triggers the release of "fight-or-flight" hormones, such as epinephrine and norepinephrine, by the endocrine system. Unlike neural transmissions, hormones require time to travel through the bloodstream to the target cells; Thus, both systems contribute to maintaining homoeostasis.
