Solved in 2 steps
- Describe the functions performed by the placenta for the developing embryo, and in each case, explain the mechanism that allows it to perform such function.In severe cases of endometriosis, endometrial tissue is found within the peritoneum. How can endometrial tissue from the uterus end up in the peritoneum?What is the outer layer (outer cell mass) of the blastocyst termed Trophoblast O Embryoblast Epiblast Hypoblast
- What is the outer layer of trophoblast termed* Cytotrophoblast Extra-embryonic mesoderm O Syncytiotrophoblast Connecting stalkThe single uterus (womb) anchors and nourishes the developing fetus. Its walls are composed of 3 layers of tissues, respectively the perimetrium (outer thin cover), the myometrium (thick layer 2 of smooth muscles, which contract to deliver the baby), and the endometrium (inner glandulartissue that lines the internal uterus cavity and undergoes cyclical changes during the menstrual cycle). The uterus lower part is called the cervix and its cavity is called the cervical canal.The oviducts, also called the Fallopian tubes (10-12 cm long), transport the ovocytes released from the ovaries to the uterus by peristalsis. The oviducts are not attached to the ovaries. Instead, the exhibit a funnel-shaped extremity, dubbed the infundibulum, that opens with finger-likeprojections to the ovaries in order to collect the emitted ovocyte. The remaining parts of the Fallopian tubes are named respectively the ampulla (the longest part of a Fallopian tube), and the isthamus(the part of the Fallopian…List the four primary tissue types of the adult body and identify which of the three primary germ layers of the embryo predominantly gives rise to each?
- Describe the structure of the placentaIn menstruation, the functional layer is shed from the endometrium. Explain the hormonal and physical factors responsible for this shedding. (See Figure 25.19.)Explain how the three germ layers are involved in forming the extraembryonic membranes, and discuss the importance of the placenta as an endocrine organ.
