Length: About 5.5 inches. Weight: About 6 ounces. Bones: Starting to harden.
Oh, the things that are transpiring in your uterus. Eyes are sensing light through thin eyelids, ears are hearing music you play in the car, and the skeleton is starting to ossify into what we know as bone.

- Taste buds -- They're now developed enough to distinguish between the bitterness of your morning decaf coffee and the sweetness of your late-night chocolate treat.
- Nerve protection -- A coating called myelin is forming around delicate nerves.
- Gender development -- Girls are well on their way to having the sex organs they'll be born with, like properly positioned fallopian tubes. Theoretically, you could see a vagina or penis at an ultrasound this week, but only if the positioning is just right (and it often isn't).
