The early development of theskeletal system begins in the third week after conception with the formation of the notochord (a rod-like structure along the back of the embryo that later becomes the spine, spinal cord, and brain), followed in the fourth week by the first signs of arms and legs. Between the fifth and eighth weeks, the limbs (first the arms, hands, and fingers, followed by the legs, feet, and toes) begin to extend and take on a definite shape.By the end of the fifth week, the embryo has doubled in size and has grown a tail-like structure By the seventh week the embryo is about 2 cm (1 in) long and facial features are visibleAt this stage, the 206 bones of the human body are all set down, in surprisingly adult form. hope this info helps xx
