Foetus. Skeleton of a 16 week old human foetus. Hardened bone appears yellow here. Gaps between the ends of bones,such as the ribs and spinal column,are filled with cartilage (not seen) that forms a matrix upon which hard bone forms. The pelvis (lower centre) and right leg (lower right) are seen. At this stage of development the foetus weighs 200 grams and has a crown-rump length of up to 14 centimetres.
