Motion and Sensation

Guión: The fetus can also grasp an object, move the head forward and back, open and close the jaw, move the tongue, sigh, and stretch.

Nerve receptors in the face, the palms of the hands, and the soles of the feet can sense light touch.

"In response to a light touch on the sole of the foot," the fetus will bend the hip and knee and may curl the toes.
