Pregnant Woman at 39 Weeks, Lateral View (Brown Skin)

Description

A lateral cutaway of a pregnant woman at 39 weeks of gestation reveals the distended uterus occupying the abdominal cavity from the pelvic brim to the level of the lower ribs, with the maternal abdominal wall rendered translucent. The fetus lies in cephalic presentation, head engaged in the pelvic inlet and flexed onto the chest, with the spine curved along the anterior uterine wall and the limbs drawn up in the fetal attitude typical of term. The coiled umbilical cord passes from the fetal abdomen toward the placenta on the uterine wall, while the amniotic cavity surrounds the fetus. Maternal landmarks include the lumbar vertebrae and sacrum posteriorly, the pubic symphysis anteriorly, and the compressed urinary bladder and rectum displaced by the presenting part. At 39 weeks the pregnancy is full term, and this profile is the standard reference for assessing lie, presentation and engagement before labour. The relationship between the fetal head and the maternal pelvic inlet underlies clinical station assessment, Leopold manoeuvres and decisions about mode of delivery, while the crowding of the bladder and rectum explains urinary frequency, pelvic pressure and constipation reported in late pregnancy. Elevation of the diaphragm by the fundus accounts for reduced tidal excursion and dyspnoea, and lumbar lordosis with sacral counter-rotation contributes to low back and pelvic girdle pain. Placental position and cord course in this cutaway also frame discussion of cord compression and third-stage management. The image suits obstetric and midwifery teaching sequences on fetal growth and presentation, antenatal class handouts, and patient-facing material explaining what the final week of pregnancy looks like from the inside. It serves as a series endpoint alongside the earlier embryonic and fetal weeks, and works well for textbook figures, hospital information leaflets, app content and editorial features on labour and birth preparation.
