What else can I help you with?
Combination of embryonic and maternal tissue?
The placenta results from the combination of embryonic and maternal tissue. The fetal portion of the placenta develops from the outer layer of the blastocyst, while the maternal portion is derived from the lining of the uterus. Together, these tissues form a vital connection between the developing fetus and the mother to facilitate nutrient exchange and waste removal.
The portion of the embryonic disk that eventually becomes the digestive system and the respiratory system is the?
endoderm
What part of the uterus will become the maternal portion of the placenta?
The part of the uterus that becomes the maternal portion of the placenta is the decidua basalis. This area is located in the endometrium, the inner lining of the uterus, and it thickens in preparation for implantation of the embryo. The decidua basalis interacts with the trophoblast cells of the developing placenta to facilitate nutrient and gas exchange between the mother and the fetus.
What portion of the placenta is from the fetus?
chorion
The part of the uterus that will become the maternal portion of the placenta?
The decidua basalis portion of the endometrium
What are myotommes?
the portion of an embryonic somite from which skeletal musculature is produced
The extraembryonic membrane that forms the fetal portion of the placenta is the?
The chorion.
The blank develops into the fetal portion of the placenta?
The chorion develops into the fetal portion of the placenta. It plays a crucial role in nutrient and gas exchange between the mother and the fetus during pregnancy.
What is the abnormal implantation of the placenta in the lower portion of the uterus known as?
The abnormal implantation of the placenta in the lower portion of the uterus is known as placenta previa. This condition can lead to complications during pregnancy and delivery, as the placenta may obstruct the birth canal. It is typically classified into different types based on how much the placenta covers the cervix. Management often involves monitoring and, in some cases, cesarean delivery if the placenta remains low-lying close to the due date.
What will the neural tube become?
The brain and spinal cord. The cephalic portion of the nueral tube becomes the brain, the caudal portion becomes the spinal cord.
What is a velamentous insertion of the cord?
its when the portion of the umbilical cord that connects to the placenta has no protection at all and it is exposed and vulnerable to ruptures. look for vasa previa
The portion of the sternum that is made of cartilage in children?
The portion of the sternum that is made of cartilage in children is the xiphoid process. This cartilaginous portion eventually ossifies and becomes bone in adulthood.
