Muscle anatomy of a pregnant woman's torso based on segmented human data. Two muscle types are depicted skeletal muscle of the arms, legs and torso and the smooth muscle of the intestines, bladder and uterus. The chorion plexus which nourishes the fetus is visible. The fetus lies in the placental sac, its head pushing against the bladder. Although the system of skeletal muscles is in place at birth, it takes several years for mature movement patterns to develop.
