Fetal movement refers to motion of a fetus caused by its own muscle activity. Locomotor activity begins during the late embryological stage, and changes in nature throughout development. Muscles begin to move as soon as they are innervated. These first movements are not reflexive, but arise from self-generated nerve impulses originating in the spinal cord. As the nervous system matures, muscles can move in response to stimuli.
