Fetus at Gestational Week 22

Description

Profile view frames a pregnant female torso in lateral section, with the gravid uterus occupying the anterior pelvis and lower abdomen beneath the rib cage. Within the uterine cavity, a 22-week conceptus is shown in cephalic presentation, the fetal head oriented inferiorly toward the maternal cervix while the trunk and flexed limbs curve superiorly. Placental tissue appears apposed to the uterine wall, with the umbilical cord coursing from the fetal abdomen to the placenta, and the bony pelvis provides a clear inferior boundary for the uterine segment. Around gestational week 22, fetal proportions change quickly, and the “slender” habitus aligns with limited subcutaneous fat and ongoing longitudinal growth, a point that often confuses learners comparing ultrasound biometry to newborn appearance. Cephalic positioning in mid-gestation also helps explain why fetal lie and presentation remain dynamic until later, and it gives a clean anatomic framework for discussing cervical competence, preterm labor risk, and how the lower uterine segment relates to the cervix as pregnancy advances. This is a teaching-friendly cutaway. It orients obstetric anatomy without relying on imaging artifacts. Use this illustration in embryology and reproductive anatomy curricula to anchor week-by-week development, or in obstetrics and midwifery teaching to introduce fetal presentation, placental location, and maternal pelvic landmarks in a single view. It also fits patient education materials explaining where the fetus sits within the womb at mid-pregnancy and why fetal movement and position changes are expected at this stage.
