Fetal Stage at Week 37 With the Placenta Omitted

Description

Shown at 37 weeks’ gestation, the human fetus is presented in a flexed fetal position with the spine in gentle kyphosis and the hips and knees drawn toward the anterior thoracoabdominal wall. Craniofacial contours are defined, with the eyelids closed, the auricles formed, and the mandible positioned inferior to the maxilla, while the upper limbs are flexed at the elbows and wrists with individual digits visible. Distally, the feet are plantarflexed with clearly separated toes, and the overall body habitus reflects late gestational subcutaneous tissue and mature limb proportions. No placenta is included. At this stage of development, external anatomy closely approximates the term neonate, so surface landmarks such as the pinna, nasal bridge, and digital creases become reliable teaching references for fetal maturation rather than organogenesis. Omitting the placenta keeps attention on fetal size, posture, and proportional growth, which is useful when correlating gestational age with expected appearance and when explaining why late third-trimester constraints drive the typical tucked posture. It also supports clinical discussions around term versus late-preterm delivery and the common bedside language of crown to rump length and overall fetal habitus, even when precise biometry comes from ultrasound. Medical educators can place this figure into embryology and obstetrics curricula to contrast late gestation with earlier embryonic stages, and perinatal teams can use it in patient-facing materials that explain what a fetus looks like near term without introducing placental anatomy. It also fits well in textbooks and review articles on human gestation, fetal growth restriction, and counseling for delivery planning around week 37.
