What attaches to the uterine lining?
-
The blastocyst
-
Progesterone
-
The secondary oocyte
-
The zona pellucida
Correct Answer
A. The blastocystExplanation
The blastocyst attaches to the uterine lining during implantation. Implantation is a crucial step in pregnancy where the blastocyst, which is a structure formed after fertilization, embeds itself into the uterine wall. This attachment allows the blastocyst to receive nutrients and oxygen from the mother's blood supply, facilitating further development and growth.Rate this question:

What stimulates contractions of the uterus after birth?
-
HCG
-
Estrogen
-
Progesterone
-
Oxytocin
Correct Answer
A. OxytocinExplanation
Oxytocin stimulates contractions of the uterus after birth. Oxytocin is a hormone produced by the pituitary gland and it plays a crucial role in the childbirth process. It stimulates the muscles of the uterus to contract, helping to expel the placenta and reduce bleeding after delivery. Oxytocin is also responsible for the bonding and attachment between mother and baby, as it is released during breastfeeding and promotes the let-down reflex.Rate this question:

What are the stages of prenatal development? (in chronological order)
-
Fetal, embryonic, preembryonic
-
Preembyronic, fetal, embryonic
-
Preembyronic, embryonic, fetal
-
Embryonic, preembryonic, fetal
Correct Answer
A. Preembyronic, embryonic, fetalExplanation
The correct answer is "preembyronic, embryonic, fetal." Prenatal development begins with the preembyronic stage, which lasts from conception to about two weeks. During this stage, the zygote undergoes rapid cell division and begins to implant into the uterine wall. The embryonic stage follows, lasting from about two to eight weeks. During this stage, the major organs and body systems begin to form. Finally, the fetal stage occurs from about eight weeks until birth. During this stage, the organs continue to develop and mature, and the fetus grows in size and complexity.Rate this question:
