It is so choked by intermingling villi and their branches that its continuity is lost on gross inspection. |
|
Anchoring villi extend outward from the fetal side and fuse with the decidua basalis to hold the organ's shape. |
|
The chorionic villi are structures around the amniotic sac that develop into the placenta. |
|
In many people, these villi are covered or clogged by mucoid plaque making it difficult for the body to absorb the necessary nutrients properly. |
|
The villi in celiac patients have collapsed and fail to absorb nutrients. |
|
Another feature of the mucosa that greatly multiplies its surface area is that of tiny projections called villi. |
|
The large number of villi give the internal intestinal wall a velvety appearance. |
|
The epithelium of the small intestine forms projections called villi, which are interspersed with small pits called crypts. |
|
Cells are continuously produced in the crypts, migrate onto the villi, and are eventually shed into the lumen of the intestine. |
|
The chorionic villi cause the mother's blood vessels in their vicinity to rupture, and the villi become bathed directly in maternal blood. |
|
|
The two procedures, amniocentesis and chorionic villi sampling, both involve putting a needle into the abdomen to withdraw the fluid. |
|
Instead of a fluid sample, a small sample of tissue called chorionic villi is collected. |
|
Trophozoites are normally attached to the surface of the intestinal villi, where they are believed to feed primarily upon mucosal secretions. |
|
From 7 to 16 days postconception, the yolk sac develops and early development of the primary chorionic villi takes place. |
|
These differ from the chorioallantoic placentae of placentals, however, in that they have no villi, which effectively reduces the intimacy of contact between fetus and mother. |
|
Between five and seven days after ovulation, the fertilised egg implants into the wall of the uterus and produces root-like outgrowths called villi. |
|
The extracellular matrix of chorionic villi can be decreased, and the villous cores, thus, as pale as the intervillous space. |
|
Placenta accreta is defined as the abnormal presence of villi attached to the myometrium due to a defect in the decidua basalis. |
|
Moreover, some reports indicate that the villi and microvilli of intestinal mucosa can affect the secretion of digestive enzymes. |
|
In the same year, he entered Le villi in a competition for one-act operas. |
|
In the case of celiacs, who have an autoimmune disease, eating gluten destroys the little hair-like villi in the small intestines. |
|
The small intestine's capacity for absorption is increased by millions of fingerlike projections called villi, which line the inner walls of the small intestine. |
|
Microscopically, histiocytes were abundant in the maternal space and were noted within the fetal chorionic villi. |
|
These fingerlike processes of the arachnoid, called arachnoid villi or arachnoid granulations, are involved in the passage of cerebrospinal fluid from the subarachnoid space to the dural sinuses. |
|
Chorionic villus sampling, which consists in sampling trophoblasts from foetal villi which link the child to the maternal placenta, is still experimental. |
|
For a diagnosis during early pregnancy, tissue of the unborn child must be obtained either by a chorion villi biopsy in the 10th to 12th pregnancy week or by an amniocentesis in the 13th to 16th week. |
|
In all 5 untreated coeliacs as well as the 3 partially treated coeliacs who were in relapse at the time of biopsy, villi were entirely absent. |
|
Five measurements in each villus and five villi were measured in each slide. |
|
During the third week of pregnancy, the syncytiotrophoblast forms a single layer of cells covering the growing villi and lining the syncytial lacunae or small cavities between the villi. |
|
The small intestine has millions of finger-like projections in the lumen called villi, lined by single layer of epithelial enterocele cells. |
|
|
Since the methylation status of the FMR-1 gene is often not yet established in chorionic villi at the time of sampling, the chorionic villus sampling results must be interpreted with caution. |
|
Intracranial meningioma originates from the arachnoid membrane cap cells where it covers the outer layer of the arachnoid mater and the arachnoid villi. |
|
Due to absent or incomplete vascularization of villi in complete hydatidiform mole, and the probable absence of D antigen on the villous trophoblast,54 the risk of Rh alloimmunization in molar pregnancy is minimal. |
|
Further refinement of this basic structure continues until term, at which time there are approximately 50 to 60 primary fetal stem villi branching into several terminal or tertiary villi. |
|
If the food is too stodgy, too 'solid,' it cannot enter the villi. |
|
Every calf should be fed fermentable material, appropriate in quality and sufficient in quantity to maintain the microbial flora of the gut, and sufficient fibre to stimulate the development of villi in the rumen. |
|
Glutamine supplementation may help reduce the risk of atrophy of villi. It may also be beneficial during convalescence after a period of digestive problems. |
|
The inflammatory reaction in the small intestine causes damage to the villi in the small intestine and can lead to total villous atrophy in celiac disease. |
|
If the villi are damaged, the person cannot absorb nutrients properly and ends up malnourished, no matter how much he or she eats. |
|
The outer epithelial layer of the chorionic villi is made up of multinucleated syncytiotrophoblast cells, which are produced from the fusion of supporting cytotrophoblast cells. |
|
The inflammations in the intestinal region can cause destruction of the intestinal villi, severely impairing the absorption of nutrients into the blood. |
|
Six months prior to admission, she underwent a suction curettage for a presumed incomplete abortion with pathology showing some hydropic changes of the villi. |
|
Maternal blood bathes the chorionic villi within the intervillous space, delivering nutrients and oxygen, and removes nutrient-depleted blood via maternal veins. |
|
Pacchionian granulations are hypertrophic arachnoidal villi, which can erode through cranial bone, causing lytic lesions on skull roentgenograms or computed tomography scans. |
|
Placental chorionic villi from maternal decidua, blood clots and mucus were dissected under a dissecting microscope into fragments a few millimetres in size. |
|
It has been proposed that a breach in the trophoblast layer lining the chorionic villi may result in contact of Hofbauer cells with maternal blood and amniotic fluid. |
|
There was no evidence of chorionic villi on either specimen. |
