Pregnant Woman at Week 37, Lateral View (Black Skin)

Description

Seen from the side with the abdominal wall opened, this rendering shows a term pregnancy at 37 weeks of gestation. The fetus lies in cephalic presentation within the amniotic cavity, its head engaged low in the maternal pelvis above the pubic symphysis, spine curved anteriorly and limbs flexed against the trunk. The umbilical cord loops from the fetal abdomen upward toward the uterine fundus, which now reaches close to the costal margin and displaces the small intestine superiorly and posteriorly. Faintly rendered maternal structures include the urinary bladder anterior to the uterus, the rectum and vagina posteroinferiorly, the sacrum, lumbar vertebrae, lower ribs and pelvic bones, giving the spatial context of the gravid uterus within the trunk. The lateral perspective is the standard way to communicate fetal lie, presentation and engagement, all of which are assessed clinically in late third-trimester antenatal visits by abdominal palpation and Leopold manoeuvres. It also demonstrates why term pregnancy produces bladder compression and urinary frequency, upward displacement of the diaphragm with reduced tidal excursion, gastro-oesophageal reflux and lumbar lordosis with associated low back pain. The relationship between the fetal head, the sacral hollow and the pubic symphysis underpins discussion of pelvic inlet dimensions, station and the mechanics of the first stage of labour. This figure suits obstetric and midwifery teaching sets, antenatal class handouts and patient-facing material explaining what happens in the final weeks before birth. It also serves textbook and journal figures on fetal presentation, ultrasound and clinical examination training resources, and app or website content tracking pregnancy week by week alongside the earlier gestational stages in this series.
