Final answer:
The reaction time for endocrine effects is not generally measured in milliseconds, it is slower compared to nerve impulses. Endocrine hormones are circulated through the bloodstream, taking as long as the blood takes to flow through the body.
Step-by-step explanation:
The statement is False. The reaction time for endocrine effects is not generally measured in milliseconds. In fact, endocrine hormones are slower to take effect compared to nerve impulses. While nerve impulses can travel at speeds greater than 100 meters per second, endocrine hormones travel through the bloodstream and can only travel as quickly as the blood flows through the cardiovascular system.
