Physical examination shows a uterus consistent in size with a 26-week gestation. Fetal ultrasonography shows a male fetus with a thick band constricting the right lower arm; the limb distal to the constrictive band cannot be visualized. The most likely condition is an example of which of the following embryological abnormalities?? A: Deformation, B: Agenesis, C: Disruption, D: Malformation, E: Aplasia,  <response>: This is a question about embryological abnormalities in fetal development. The key details in the stem are that there is a thick constrictive band on the right lower arm of the fetus, causing the distal limb to not be visible on ultrasound. This describes a condition called amniotic band syndrome, which is caused by strands of the amniotic sac wrapping around and constricting parts of the fetus. Amniotic band syndrome is considered a disruption sequence, as normal embryonic development is disrupted by extrinsic factors after initial formation. Therefore, the correct answer is C - Disruption.C: Disruption
