A kick chart is a form or graph used by a pregnant woman in the later stages to record the activity of her fetus. [1] If too few kicks are felt within a specified time (usually 12 hours) this could indicate a problem. [1] A frequent question posed by midwives is how "many times has the baby kicked in the last twelve hours?"
Ventriculomegaly is a brain condition that mainly occurs in the fetus when the lateral ventricles become dilated. The most common definition uses a width of the atrium of the lateral ventricle of greater than 10 mm. [ 1 ] This occurs in around 1% of pregnancies. [ 2 ]
A study of 32 normal pregnancies showed that fetal heart motion was visible at a mean human chorionic gonadotropin (hCG) level of 10,000 UI/L (range 8650–12,200). [19] Obstetric ultrasonography can also use Doppler technique on key vessels such as the umbilical artery to detect abnormal flow.
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage resulting in the presence of shunts to move oxygenated blood and ...
Stroke volume will normally be in the range of 70–80 mL. Since ventricular systole began with an EDV of approximately 130 mL of blood, this means that there is still 50–60 mL of blood remaining in the ventricle following contraction. This volume of blood is known as the end systolic volume (ESV). [1]
In vertebrates, the ventricular zone (VZ) is a transient embryonic layer of tissue containing neural stem cells, principally radial glial cells, of the central nervous system (CNS). [ 1 ] [ 2 ] The VZ is so named because it lines the ventricular system , which contains cerebrospinal fluid (CSF).
A partogram or partograph is a composite graphical record of key data (maternal and fetal) during labour entered against time on a single sheet of paper. Relevant measurements might include statistics such as cervical dilation, fetal heart rate, duration of labour and vital signs. [1] In, 1954 Friedman prepared the cervicography. [2]
