Compared to neural signals, hormonal signals generally have what characteristic?

• A. Slower onset but longer duration
• B. Faster onset and shorter duration
• C. Same speed and duration
• D. Hormonal signals are unrelated to duration

Answer: (A)

When comparing how signals move through the body, neural communication is fast and targeted, delivering quick, precise responses through electrical impulses and neurotransmitters across synapses. Hormonal communication, however, travels through the bloodstream to reach distant tissues. This journey makes the onset slower, and once hormones exert their effects, those effects tend to last longer because hormones can persist in circulation and often influence cells for extended periods, sometimes by altering gene expression. An example is cortisol, which rises gradually under stress and can affect metabolism and immune function for hours after the initial trigger. So, the hallmark difference is a slower onset with longer duration.
