Fetus at Week 11 in the Uterus - Brown Skin

Description

Fetus at 11 weeks’ gestation occupies the uterine cavity in a lateral profile, with the head proportionally large relative to the trunk and the developing limbs flexed close to the body. The placenta is contiguous with the uterine wall, and the umbilical cord courses from the fetal abdominal wall toward the placental disc, crossing the amniotic space. Surrounding uterine structures are readable in relation to the gestational sac, with the myometrium forming the outer muscular wall and the endometrial surface representing the maternal side of placentation. Brown fetal skin tone is presented for inclusive obstetric and embryology resources. Week 11 sits at the transition from embryonic to fetal staging, so this illustration supports teaching of organogenesis completion, early fetal proportions, and placental anatomy before the second-trimester growth spurt. The fixed lateral orientation helps correlate gross relationships commonly evaluated on first-trimester ultrasound, including placental location relative to the uterine fundus and the course of the umbilical cord within the amniotic cavity, while keeping pelvic anatomy legible for clinical counseling and documentation. It also provides a solid anatomical backdrop for discussions of early pregnancy loss, subchorionic hematoma location, and the sampling target for chorionic villus sampling in the late first trimester. Obstetrics and gynecology educators can pair this illustration with timelines of crown-rump length, nuchal translucency screening windows, and early placental development, while medical publishers can use it to anchor chapters on gestation and maternal-fetal interface anatomy. It also fits patient-facing materials on first-trimester development when clinicians want a uterus-based context rather than an isolated fetus.
