Select every statement that is TRUE about the endocrine system.
Hints
- Two options are misconceptions - one about speed, one about which gland does sex hormones.
- The endocrine system is SLOWER than the nervous system, and the GONADS (not the thyroid) release sex hormones.
Show the answer
- C. A surge of adrenaline reaches every tissue at once, because it travels by blood rather than by nerve.
- D. The thyroid sets the body's baseline metabolic rate.
- E. Hormones act faster than nerve signals because they travel in the blood.
Why
Hypothalamic control of the pituitary, bloodborne hormones, and cortisol's negative feedback are true. The endocrine system is slower than the nervous system, and the gonads (not the thyroid) release sex hormones - so those are false.
