Pregnant Woman at 28 Weeks of Gestation, Lateral View (Brown Skin)

Description

Seen from the side, the maternal torso is rendered semi-transparent so the gravid uterus can be followed from the fundus, now well above the umbilicus, down to the cervix. Inside the amniotic sac the third-trimester fetus lies in cephalic presentation, head directed toward the pelvic inlet with the spine curved along the anterior maternal abdominal wall and the limbs flexed against the trunk. The umbilical cord loops between the fetal abdomen and the placental wall implanted along the uterine surface. Beneath and behind the presenting part, the maternal bony pelvis and sacrum, the compressed urinary bladder and the cervical canal establish the spatial relationships of late gestation. At around week 28 the fetus has usually assumed a longitudinal lie, and this lateral projection is the standard way to teach presentation, lie and station, the parameters assessed by Leopold manoeuvres and by transabdominal ultrasound at third-trimester visits. The image also makes visible the mechanics behind common late-pregnancy symptoms: fundal elevation with diaphragmatic displacement and reduced tidal excursion, bladder compression with urinary frequency, and lumbosacral loading that produces the characteristic posture with a hand supporting the low back. Cervical length and the closed internal os are relevant references when discussing preterm labour risk, and the placental position matters for delivery planning. The illustration suits obstetric and midwifery teaching sequences, antenatal class handouts and patient-facing material explaining what happens during the third trimester, particularly when used alongside the earlier weeks of the same series to demonstrate progressive uterine growth and fetal orientation. It also serves textbook and journal figures on fetal presentation, nursing and paramedic training modules, and editorial or app content for expectant parents.
