During birth following events happen. Which one of the following is the correct sequence of these events from start to end?1- Rupturing of amniotic sac2- Contraction of myometrium3- Cutting of umbilical cord4- Inhibition of progesterone secretion

Explanation

The correct sequence is 4, 2, 1, 3.1. Inhibition of progesterone secretion occurs first, triggering the onset of labor by removing the inhibitory effect of progesterone on uterine contractions.2. Contraction of the myometrium follows, initiating the active phase of labor, which helps push the fetus through the birth canal.3. Rupturing of the amniotic sac occurs next as a result of increasing pressure from uterine contractions, leading to the release of amniotic fluid and the "breaking of water."4. Cutting of the umbilical cord is the final event, typically done after the baby is born and has taken its first breath, separating the baby from the placenta and completing the birthing process.
