Compared with nervous coordination, endocrine coordination is:
Aslower acting and longer lasting
Bfaster acting and shorter lasting
Cfaster acting and longer lasting
Dslower acting and shorter lasting
Answer & Solution
Correct answer: A. slower acting and longer lasting
1. Nervous coordination sends electrical impulses along neurones, which travel in milliseconds.
2. Endocrine coordination sends hormones through the bloodstream, which takes seconds to minutes.
3. So the endocrine route is the slower of the two.
4. A nerve impulse stops as soon as stimulation stops, giving a brief effect.
5. A hormone persists in the blood until it is broken down, so its effect lasts far longer.
