Pregnant Woman at 37 Weeks, Lateral View (Asian Skin)

Description

A lateral projection of a pregnant woman near term shows the gravid uterus opened to reveal a fetus at gestational week 37 lying in cephalic presentation, the vertex directed toward the pelvic inlet and the occiput engaged behind the maternal symphysis. The fetal spine curves along the maternal anterior abdominal wall, with the limbs flexed tightly against the trunk in the characteristic attitude of late gestation, and the umbilical cord looping through the remaining amniotic cavity. The uterine wall is markedly thinned and stretched over the fetal contour, while the fundus reaches the level of the lower ribs and displaces the maternal viscera superiorly. Deeper in the section, the cervix, vagina, urinary bladder anteriorly, rectum posteriorly, sacrum and lumbar vertebrae define the bony and soft-tissue boundaries of the birth canal. Week 37 marks the transition to early term, and this view illustrates the anatomical relationships that determine labour: fetal lie, presentation, engagement of the vertex and the alignment of the cervical canal with the pelvic axis. It supports discussion of fundal height measurement, Leopold manoeuvres, cervical effacement and dilatation, and the compression of the urinary bladder and rectum that produces frequency and pelvic pressure in the third trimester. The same anatomy underlies decision-making around malpresentation, external cephalic version, epidural placement relative to the lumbar vertebrae, and the approach used in lower segment caesarean section. Suited to obstetric and midwifery teaching material, antenatal class handouts and week-by-week pregnancy series in print and online, where a single lateral cutaway conveys both fetal position and maternal pelvic anatomy. It also serves textbook and journal figures on term pregnancy, labour mechanics and prenatal counselling, and gives clinicians a clear reference image when explaining presentation and delivery planning to expectant parents.
