________ causes contraction of the smooth muscle in the wall of the uterus. It also stimulates the ejection of milk from the lactating breast.

Oxytocin causes contraction of the smooth muscle in the wall of the uterus. It also stimulates the ejection of milk from the lactating breast.

Yes.

The hormone that causes contraction of the smooth muscle in the wall of the uterus and also stimulates the ejection of milk from the lactating breast is called oxytocin.

To arrive at this answer, you can:

1. Recall prior knowledge: If you have learned about female reproductive anatomy and physiology, you may remember that oxytocin is involved in both uterine contractions during labor and milk letdown during breastfeeding.

2. Consult a reliable source: You can refer to reputable textbooks or medical resources that discuss the role of hormones in reproductive physiology. This can provide you with accurate information about the function of oxytocin in uterine contractions and milk ejection.

It's important to ensure you have accurate and up-to-date information by referring to reliable sources or consulting with a healthcare professional.
