The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...
Amniotic fluid index (AFI) is a quantitative estimate of amniotic fluid [1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [1] AFI is the score (expressed in centimetres) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus.
Often referred to as the "water" which surrounds an unborn baby, amniotic fluid plays a vital role in fetal development. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please ...
Oligohydramnios is a medical condition in pregnancy characterized by a deficiency of amniotic fluid, the fluid that surrounds the fetus in the abdomen, in the amniotic sac. The limiting case is anhydramnios , where there is a complete absence of amniotic fluid.
The presence of these biophysical variables implies absence of significant central nervous system hypoxemia/acidemia at the time of testing. By comparison, a compromised fetus typically exhibits loss of accelerations of the fetal heart rate (FHR), decreased body movement and breathing, hypotonia, and, less acutely, decreased amniotic fluid volume.
Amniotic cavity in human embryo 1.3 mm. long. The amniotic cavity is the closed sac between the embryo and the amnion, containing the amniotic fluid. The amniotic cavity is formed by the fusion of the parts of the amniotic fold, which first makes its appearance at the cephalic extremity and subsequently at the caudal end and sides of the embryo ...
Amniotic fluid is mildly basic (pH 7.1–7.3) compared to normal vaginal secretions which are acidic (pH 4.5–6). [10] Basic fluid, like amniotic fluid, will turn the nitrazine paper from orange to dark blue. [9] Fern test: A sterile cotton swab is used to collect fluid from the vagina and place it on a microscope slide.
According to the Cleveland Clinic, dyscalculia is a learning disorder affecting a person's ability to understand "number-based information and math." "The symptoms of this disorder usually appear ...
