Description

Examine the 5-week human embryo with this detailed 3D model, highlighting continued organ development and body curvature. It demonstrates rapid brain growth with division into primary vesicles, further limb bud development, and visible optic and otic structures. The pharyngeal arches are more pronounced, and the heart shows clear external prominence. This model is ideal for visualizing how embryonic features become increasingly recognizable as distinct anatomical systems begin to form and organize.
