Fetal Weight Standard
Week 6 brings rapid structural transformation. The neural tube completely closes over the spinal cord. Tiny bud-like paddles emerge on the torso, which will rapidly lengthen into arms, hands, legs, and feet.
The fetal heart is now beating at approximately 100 to 115 beats per minute—nearly double the adult resting heart rate. Facial features take shape with dark pigment dots for eyes and tiny depressions for nostrils and ears.
