Pregnant Woman at 36 Weeks of Gestation, Lateral View (Brown Skin)

Description

Shown in profile, the maternal torso is rendered semi-transparently so the gravid uterus fills the abdomen from the pelvic brim to well above the umbilicus, its fundus displacing the large intestine posteriorly and superiorly. Within the amniotic cavity the fetus lies in cephalic presentation, head engaged toward the pelvic outlet with the spine curved anteriorly, limbs flexed against the trunk, and the umbilical cord looping between the fetal abdomen and the uterine wall. The placenta is seen applied to the uterine lining, while the urinary bladder sits anteroinferior to the presenting part and the rectum and sacrum define the posterior pelvic boundary. The maternal hand resting on the lower back and the forward tilt of the lumbar spine convey the postural change of late pregnancy. At approximately 36 weeks the fetus has usually assumed a longitudinal lie with vertex presentation, the arrangement that determines suitability for vaginal delivery, and this lateral projection is the standard way to demonstrate engagement, fundal height and the relationship of the presenting part to the pelvic inlet. It also explains common third-trimester complaints: bladder compression and urinary frequency, gastric reflux from upward displacement of abdominal viscera, constipation from bowel compression, and lumbar lordosis with low back pain. The same view underpins discussion of Leopold manoeuvres, breech versus cephalic assessment, and planning for external cephalic version when malpresentation persists. The image suits obstetric and midwifery teaching sets, antenatal class handouts and patient-facing material explaining fetal position before labour, as well as embryology and developmental anatomy atlases where it completes a week-by-week series. Publishers, clinic websites and prenatal app developers can use it as a clear reference figure for the late third trimester. Anatomical accuracy verified by SciePro's Medical Advisory Board.
