The placenta.

The umbilical arteries carry blood from the fetus to the placenta.

Aims: The objective of this study was to determine whether the maternal surface of the placenta is fractal, and whether the mean fractal dimension differs according to the gestational age and clinically or pathologically different conditions. The placenta is the connective tissue that connects the fetus to the mother. (Remember that in the placenta substances are exchanged between fetal and maternal blood, but the blood itself does not mix.)

Placental secreted EVs are important in feto-maternal communication and have been identified in maternal blood. Seen in primates and rodents.

After the blastocyst which will develop into the fetus makes contact with the uterine wall, blastocyst and maternal tissue grow together to form 9.4: Anatomy of the placenta Later on in pregnancy, it is primary produced by the foetus in the form of Anatomical Variations urine (700 to 800ml) and lung fluid with These are the following variations: the average volume at term 700 to o Succenturiate lobe: a separate 800ml. In the first trimester, it is likely a transudate of maternal or fetal plasma. Complete placenta previa: occurs when the placenta completely covers the internal os.

See if your slide contains maternal tissue (most slides do not).

The placenta is unique in that it is an organ which arises from the tissue of two genetically distinct organisms; part of the placenta develops from the tissue of the mothers uterine wall, while another part develops from the fetus own tissue.

Oxygen and nutrients in the maternal blood in the intervillous spaces diffuse through the walls of the villi and enter the fetal capillaries. Maternal surface-the maternal surface has a dull red color and it feels rough and spongy. The branched vessels are embedded in a stromal core covered by trophoblast cells which are completely bathed in Greatest diameters and thickness are measured, and aberrations from round or ovoid configuration and extra lobes noted.

Nontrophoblastic, nonvascular intraplacental tumors are rare. An accessory lobe of placenta is an addition separate lobe of placenta.

The maternal uterine endometrium stromal cells (fibroblast-like) are transformed by steroid hormones (progesterone) and embryonic signals into the decidua. a The umbilical vein and arteries containing fetal blood reach the placenta at the cord insertion site and spread across the chorionic plate, branching extensively to provide the tree-like shape of the placenta. At first, the chorionic villi cover the entire surface of the chorion. Some describe 'em as white.

Diameter: 15-20 cm. Increased variability of the placental shape was associated with lower placental functional efficiency. Placenta, Umbilical Cord, and Amniotic Cavity; Defects: Of these tumors, leiomyomas within the placenta or fetal membranes are exceedingly rare, with fewer than 10 reported cases. The placenta is a temporary fetal organ that begins developing from the blastocyst shortly after implantation.It plays critical roles in facilitating nutrient, gas and waste exchange between the physically separate maternal and fetal circulations, and is an important endocrine organ producing hormones that regulate both maternal and fetal physiology during pregnancy.

A chorionic plate covers the fetal surface. Questions: Placentas are a defining characteristic of placental mammals but they are found in marsupials and some non-mammals with varying levels of development.. Development of the placenta.

Ovule orientation may be anatropous, such that when inverted the micropyle faces the placenta (this is the most common ovule orientation in flowering plants), amphitropous, campylotropous, or orthotropous (anatropous are common and micropyle is in downward position and chalazal end in on the upper position hence, in amphitropous the anatropous arrangement is tilted 90 degrees The placenta serves as an interface between the mother and the developing fetus and has three main jobs: Attach the fetus to the uterine wall. Earn . These structures will hold approximately 150 mL of maternal blood.

If so, locate the attachment of the anchoring villi to the decidua basalis at this junctional zone. These signs may indicate an aging placenta, or one that has not had a healthy maternal/fetal transfer unit.

The maternal surface of the placenta contains placental cotyledons, which are visualized on T2W images separated by thin bands of T2 hypointense signal and become more prominent with increasing gestational age.

Blood vessels radiate to the edge of the placenta (Figure 31.2). Consists of large lactiferous ducts that open to the surface of the nipple via lactiferous sinuses, which branch into ducts and terminal ductules which terminate in acini Acini are grouped together in clusters to form lobules (terminal duct lobular unit) Ductal - lobular system is arranged in series of segments (5 - 10)

At first, the chorionic villi cover the entire surface of the chorion.

The cotyledons

Fig. Each cotyledon has its own blood supply (Figure 31.1). Early cord clamping may result in the placenta being proportionally heavier, whereas delayed cord clamping can produce a placenta that is Remove cord, lay flat, and examine for number of coils (1-2 every 5 cm is normal; more than 2 per 5 cm is abnormal).

Sections should not be taken at the margin of the disc. It is encapsulated by the tunica albuginea, a dense layer of connective tissue which is covered by the germinal epithelium (Ovarian surface epithelium), a layer of simple squamous or cuboidal epithelium.The ovarian follicles, which enclose the oocytes, are primarily embedded in the Cells or substances in this fluid can be removed for prenatal diagnostic tests (amniocentesis). The grooves between lobes are occupied by placental septa, which arise from the decidua basalis and extend toward the basal plate. It is a small lobe connected to the main lobe through blood vessels.

The maternal side will have 15-20 bulging areas which are the cotyledons, covered by a thin layer of decidua basalis.

It aids in the transfer of nutrients and oxygen to the fetus and is also in charge of collecting carbon dioxide and trash from the fetus.

Bowling Green, OH 43402 (419) 352-6335.

Run your finger around the edge of the placenta to determine whether there are any vessels or succinturiate lobes in the membranes. We hypothesised that the placenta adapts differently to suboptimal maternal diets, evidenced by changes in placental morphology, developmental markers, and key transport systems. It acts as a fetomaternal organ with two components- foetal placenta (chorion) which develops from the same blastocyst that forms the fetal and maternal placenta that forms the maternal tissue. The fetal part of the placenta is made up of the chorionic plate with its placental villi, the cytotrophoblast layer and the intervillous spaces. Singleton placentas: Remove the placenta from the container, including any detached segments of umbilical cord or blood clots that may be included.
