Week 7
By week 7, the embryo measures around 10mm and the brain, head and face start to develop rapidly. Nerve cells undergo continued development as the brain and spinal cord begin to take shape. The forehead is large and the lenses of the eyes start to form. The inner ear also starts to develop and the arm buds lengthen and become paddle shaped. These will eventually develop into hands. Week 8
By week 8, the baby is referred to as a fetus. The legs form cartilage and increase in length, although leg parts such as the knees, thigh and toes are not yet distinct. Fingers have started to form, the ears have started to become shell shaped and the eyes are visible. The fetus is still contained within the amniotic sac and receives nutrients from the yolk sac, but the placenta continues to develop and forms structures that will enable it to become attached to the womb. The fetus may now be around 11 to 14mm in length.
