Fetus at Week 22 in the Uterus - Brown Skin

Description

Fetus at 22 weeks’ gestation rests in a lateral profile within the uterine cavity, with the cranial pole oriented superiorly and the flexed spine curving along the posterior uterine wall. Placenta attaches to the endometrium (decidua basalis) on one side of the uterine corpus, and the umbilical cord courses from the fetal umbilicus to the placental disc, its insertion and gentle coiling readable in a single frame. The amnion outlines the amniotic cavity around the fetus, while the surrounding myometrium defines the uterine contour within the maternal pelvis. Brown fetal skin tone is represented on the exposed body surface. At 22 weeks, the relationship between placenta, cord, and uterine wall is not just developmental anatomy, it is the framework for interpreting second-trimester obstetric findings. Placental location underlies clinical discussions of placenta previa versus normally implanted placenta, and cord configuration supports teaching points on velamentous insertion and vasa previa as causes of antepartum bleeding and fetal compromise. A fixed lateral perspective makes the spatial logic intuitive: fetal orientation relative to the uterine fundus and cervix, plus the cord’s path from the anterior abdominal wall to the placenta. Small structures read cleanly. That matters when you are explaining placental implantation and fetal positioning without relying on ultrasound artifacts. Obstetrics and gynecology lecturers can pair this illustration with mid-gestation ultrasound units to anchor terminology such as chorionic plate, decidua, and umbilical vessels, and embryology faculty can use it to frame the transition from early organogenesis to second-trimester growth. Medical publishers will find it well suited for prenatal counseling handouts and textbooks addressing placental anatomy, cord abnormalities, and fetal position in the uterus.
