Developing Baby Images - Fetal Images Created Using NASA Technology

At this point, I am still, in scientific terms, an "embryo."

From 7 to 7½ weeks, my tendons attach leg muscles to bones, and knee joints appear.

By 7½ weeks, my hands can be brought together, as can my feet.

I can kick, and will jump if startled.

By 7 to 7½ weeks, my nephrons, the basic filtration units in my kidneys, begin to form.

I am no longer called an "embryo" and am now called a "fetus."

My heart has already beaten over 7 million times. My heart began to beat 3 weeks and 1 day following fertilization.

I am now the size of a cherry tomato, have more than 4,000 body parts routinely found in newborns and adults, and possess about 1 billion specialized cells, forming nearly all components of all body systems!

I am beginning to perform occasional breathing motions.

My eyelids have begun to fuse together and completely cover my eyes.

I am now the size of a small tomato.

My face, palms of my hands, and soles of my feet now sense and respond to light touch.

My mouth opens and closes, and my tongue moves.

I am now swallowing amniotic fluid.

I can sigh, stretch, and move my head.

As a baby girl, I have early reproductive cells in my ovaries.

I have begun sucking my thumb.

I have begun grasping objects.

If touched near my mouth, my face now turns toward the side touched.

I have begun to yawn.

I am now the size of a purple-top turnip.

My body weight has increased more than 75% just this week.

My bones are hardening throughout my body.

My fingernails and toenails have begun to grow.

The right and left sides of my brain are connecting.

My unique fingerprints have begun forming.

Lightly touching one of my upper eyelids causes both eyes to roll downward.
