Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
While facing the woman, palpate the woman's upper abdomen with both hands. An obstetrician can often determine the size, consistency, shape, and mobility of the form that is felt. The fetal head is hard, round, and moves independently of the trunk while the buttocks feel softer, are symmetric, and the shoulders and limbs have small bony ...
A human fetus, attached to placenta, at three months gestational age. In humans, the fetal stage starts nine weeks after fertilization. [7] At this time the fetus is typically about 30 millimetres (1 + 1 ⁄ 4 in) in length from crown to rump, and weighs about 8 grams. [7] The head makes up nearly half of the size of the fetus. [8]
Gestational age: 35 and 0 days until 39 weeks and 6 days old. Embryonic age: Weeks nr 34–38. 33–37 weeks old. The fetus is considered full-term at the end of the 39th week of gestational age. It may be 48 to 53 cm (19 to 21 in) in length. The lanugo is gone except on the upper arms and shoulders. Fingernails extend beyond fingertips.
The earliest fetal response to a sound stimulus has been observed at 16 weeks' gestational age, while the auditory system is fully functional at 25–29 weeks' gestation. [4] At 33–41 weeks' gestation, the fetus is able to distinguish its mother's voice from others. [5] [6]

The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...
