Skeleton of a human foetus. Side view of a 14 week old human foetus,stained with alizarin to show the bony skeleton. Alizarin is a red dye used as a bone staining technique. Developing bone stains red,while cartilage (especially in the joints) is unstained. Bone development in a foetus of this age can be seen in the skull,spine,ribcage and bones of the limbs. At 14 weeks old the foetus is about 10 cm long (crown-rump length) and its weight about 150 grams. Fingers and toes are visible,with the arms more well developed than the legs. The head is proportionately large compared to the body | |
