Estrogen
The question is incomplete. There are no options given (for "which of the following") to answer this question.
Estrogen
Progesterone. When the level of progesterone drops, it causes the uterus wall to begin contracting, which pushes the baby's head into the cervix, starting the positive feedback loop of contractions in labor.
B oxytocin
Oxytocin is the hormone that is responsible for uterine contractions. This is important during labor, and sometimes the doctor will prescribe an artificial version to give to the expectant mother to start the labor process.
Oxytocin is the hormone responsible for initiating and promoting labor. Its levels increase as childbirth approaches, stimulating contractions of the uterus to help facilitate the birthing process.
The gland responsible for inducing labor is the posterior pituitary gland, which releases the hormone oxytocin. Oxytocin stimulates uterine contractions during labor, facilitating the childbirth process. Additionally, the placenta produces other hormones such as prostaglandins that also play a role in initiating and regulating labor.
Oxytocin, not Oxycontin, is the hormone responsible for stimulating strong contractions of the uterus during labor and childbirth. Its role is essential in facilitating the progress of labor and promoting the delivery of the baby. Oxycontin is a powerful pain medication that is unrelated to uterine contractions.
oxytocin
Oxytocin hormone is responsible for stimulating uterine contractions during childbirth and also plays a role in milk ejection during breastfeeding. Additionally, it is involved in social bonding and emotional regulation.
Oestrogen, or estrogen, is the primary hormone of the female reproductive system. It is responsible for menstruation, making reproduction possible by thickening the lining of the uterus, and is partly responsible for the development of breasts.
Labor is triggered by the hormone called oxytocin and prostaglandin. release of milk is triggered by the hormone prolactin.
