Fetus at Week 22 in the Uterus - Asian Skin

Description

Fetus at 22 weeks’ gestation fills the uterine cavity in lateral profile, with the calvaria and facial contour oriented anteriorly and the spine curving posteriorly along the fetal back. Placenta lines the uterine wall as a discoid organ, and the umbilical cord courses from the fetal umbilicus to its placental insertion, surrounded by amniotic fluid within the intact gestational sac. Myometrium forms the thick outer uterine layer, while the endometrial decidua lies internal to it, framing the fetoplacental unit. Asian fetal skin tone is shown across the exposed fetal surface. Week 22 sits in the second trimester anatomy-scan window, when clinicians correlate fetal biometry and organ survey with placental position and cord anatomy to refine dating and assess risk. This fixed lateral perspective helps you judge the spatial relationship of placenta to the fetus and uterine wall, a key point when discussing placenta previa versus a normally implanted placenta, or when teaching how marginal or velamentous cord insertion can complicate fetal growth and intrapartum management. The umbilical cord’s course is easy to follow. Placental topography matters. Use this illustration in obstetrics and gynecology lectures, embryology blocks on human development, or in textbooks and patient-facing materials explaining second-trimester pregnancy anatomy, including the uterus, placenta, and umbilical cord within pelvic anatomy. It also supports figures for manuscripts on placental implantation, prenatal counseling at the limits of viability, and ultrasound correlation in a lateral view.
