Fetus at Week 22 - Asian Skin

Description

Fetus at 22 weeks’ gestation appears with the placenta and umbilical cord in a single, isolated field against a white background. The fetal head sits superior to the thorax, with the flexed cervical and thoracolumbar posture typical of the second trimester, and the upper limbs lie anterior to the chest while the lower limbs extend inferiorly with recognizable thigh, leg, and foot segments. Placental tissue occupies a separate mass adjacent to the fetus, and the umbilical cord courses between them to its insertion site, with surface caliber consistent with a cord containing one umbilical vein and paired umbilical arteries. Asian skin tone is presented across the fetal integument. Proportions matter here. Week 22 occupies a practical threshold in obstetrics because biometric dating and structural screening converge in this window, and clinicians often correlate external proportions with ultrasound measurements such as biparietal diameter, head circumference, femur length, and abdominal circumference. Including the placenta and full cord supports teaching on placental location, cord insertion variants (marginal versus velamentous), and how cord length and coiling relate to entanglement risk and compromised flow, even when those details are assessed primarily by Doppler rather than gross inspection. The fixed, uncluttered background helps isolate external landmarks, so you can point out craniofacial proportion, limb flexion, and the fetal-placental relationship without competing maternal anatomy. Use this illustration in second-trimester embryology and obstetrics lectures, prenatal counseling brochures discussing the anatomy scan, or publisher plates that need a gestational-age specific fetal model with placenta and umbilical cord included in the same frame.
