Pregnancy at 29 Weeks in the Female Body, Lateral View (Caucasian Skin)

Description

Seen from the left side, the maternal torso is rendered semi-transparently so the gravid uterus fills the lower abdomen and rises well above the pelvic brim, its fundus approaching the level of the costal margin. The week-29 fetus lies in cephalic presentation, the head directed toward the pelvic inlet and the flexed spine curved along the anterior uterine wall, with the upper limbs drawn against the chest and the lower limbs folded within the amniotic cavity. The umbilical cord loops between the fetal abdomen and the placental surface, while the maternal lumbar vertebrae, sacrum and iliac bone provide the posterior frame and the urinary bladder sits compressed anterior and inferior to the presenting part. The anterior abdominal wall is distended, and the mother's hands rest on the fundus and lumbar region. A lateral projection at this point in the third trimester illustrates the spatial relationships that govern late-pregnancy assessment: fundal height measurement, Leopold manoeuvres for determining presentation and lie, and the anterior displacement of the maternal centre of gravity that produces lumbar lordosis and low back pain. The image also clarifies why bladder capacity falls and urinary frequency rises as the presenting part descends, and why supine positioning can compress the inferior vena cava. Cephalic presentation at 29 weeks is common but not yet fixed, making this a useful reference when discussing breech version, preterm labour, and fetal viability at this gestational age. Suited to obstetric and midwifery teaching sets, antenatal class handouts and patient-facing material explaining fetal position and third-trimester discomfort, as well as textbook and journal figures charting gestation week by week. It also serves prenatal ultrasound training, physiotherapy resources on pelvic and postural change in pregnancy, and campaigns from maternal health organisations.
