Human Femur
The femoral neck-shaft angle (NSA) or caput-collum-diaphyseal (CCD) angle is one of the most frequently applied measurements to assess hip morphology, in particular, the relation of the femoral shaft to the femoral head-neck axis.
Fetal Heart
The baby growing inside of the mother’s uterus (the womb) is called a fetus. The growing fetus is fully dependent on a special organ called the placenta for nourishment. One side of the placenta is attached to the uterus, and the other side is attached to a liquid-filled sac that holds the fetus. A special cord called the umbilical cord links the placenta to the fetus. The mother’s blood flows through a thin layer of cells in the wall of the uterus, giving the fetus food and oxygen while removing any wastes like carbon dioxide.
