Description

Examine the 9-week human embryo with this high-precision 3D model. The head remains large, but body proportions begin to balance. The eyelids fuse, protecting the developing eyes, while the external ears take their definitive position. Limbs lengthen, with clear finger and toe separation. The model highlights the start of ossification centers in bones, providing insight into skeletal development. This stage is ideal for studying the shift from organ formation to growth and refinement.
