The BEST way to describe the role of oxytocin in labor is:
  1. It is the hormone that is produced as a result of fear.
  2. It is the hormone that causes the uterus to contract.
  3. It slows labor.
  4. It is a natural pain reliever.
Explanation
Answer: B - Oxytocin is released in pulses, and causes the rhythmic contraction of the uterus during labor. Oxytocin engenders feelings of love and altruism, and is present in pregnancy and birth as well as during orgasm and breastfeeding, and even when sharing a meal with someone you like. Fear hormones produce the fight-or-flight response and are categorized as catecholamines. Natural pain relievers are endorphins.
