By about week 21, the fetus begins to develop a regular schedule of movement. [17] The startle reflex is present in half of all fetuses by week 24 and in all fetuses by week 28. [ 19 ] Movement is restricted around this time because the fetus has grown so large it has little space for kicking or changing body position.
Gestational age: 9 weeks and 0 days until 11 weeks and 6 days old. Embryonic age: 7 weeks and 0 days until 9 weeks and 6 days old. Fetus at 10 weeks. Embryo measures 30–80 mm (1.2–3.1 in) in length. Ventral and dorsal pancreatic buds fuse during the 8th week; Intestines rotate. Facial features continue to develop. The eyelids are more ...
For example, a fartlek training session might consist of a warm-up for 5–10 minutes; running at a steady, hard speed for 2 km; rapid walking for 5 minutes (recovery); sprints of 50–60 s interspersed with easy running; full-speed uphill for 200 m; rapid walking for one minute; repeating this routine until the time schedule has elapsed (a ...
Human embryonic development covers the first eight weeks of development, which have 23 stages, called Carnegie stages. At the beginning of the ninth week, the embryo is termed a fetus (spelled "foetus" in British English). In comparison to the embryo, the fetus has more recognizable external features and a more complete set of developing organs.
From the 10th week of gestation (8th week of development), the developing embryo is called a fetus. All major structures are formed by this time, but they continue to grow and develop. Because the precursors of the organs are now formed, the fetus is not as sensitive to damage from environmental exposure as the embryo was.

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]
A baby's chances for survival increases 3 to 4 percentage points per day between 23 and 24 weeks of gestation, and about 2 to 3 percentage points per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [16]
