Fetus at Week 21 - Caucasian Skin

Description

Fetus at 21 weeks’ gestation is presented in an alternative flexed pose with the placenta and attached umbilical cord on an isolated white field. The head is proportionally large relative to the trunk, with the upper limbs held anterior to the thorax and the lower limbs flexed at the hips and knees, allowing clear appreciation of fetal proportions typical of the mid second trimester. Placental tissue lies adjacent to the fetal body with the umbilical cord coursing from the fetal umbilicus to its placental insertion, a spatial relationship that reads well in a single frame. Caucasian skin tone is applied across the fetal integument. Week 21 marks a teaching sweet spot for correlating external morphology with obstetric imaging, because fetal biometrics (biparietal diameter, head circumference, femur length) and placental position are routinely evaluated at the anatomic survey. The cord and placental surface anatomy support discussion of velamentous or marginal cord insertion and the clinical significance of a short-appearing cord, while the fetal posture helps learners orient flexion at the cervical spine, shoulder, hip, and knee without the distractions of maternal anatomy. Fine surface detail, including developing auricular contours, limb segmentation, and subtle skin texture, also suits embryology modules that introduce lanugo and early subcutaneous fat patterns seen in the second trimester. Small fetus, big concepts. Use this illustration in preclinical embryology and human development courses, obstetrics and midwifery teaching decks, and patient-facing placental anatomy handouts where a neutral background improves labeling for the umbilicus, cord course, and placental disk. It also fits textbook figures on second-trimester milestones and prenatal counseling materials that reference week 21 morphology. Anatomical accuracy verified by SciePro's Medical Advisory Board.
