Inhibition of PTH secretion by a step manner, select the correct sequences of PTH inhibition?

#Unit 7. System Physiology – Animal
  1. Ca2+ binds to the receptor → extracellular Ca2+ concentration is increased → activates PLC → inhibits PTH secretion

  2. intracellular Ca2+ concentration is increased → binds to the receptor→ activates PLC → inhibits PTH secretion

  3. extracellular Ca2+ concentration is increased → binds to the receptor→ activates PLC → inhibits PTH secretion

  4. extracellular Ca2+ is decreased decreased → Ca2+ binding to the receptor  → inhibits PTH secretion
