The first is the fetal skull, which is much more malleable than an adult human skull, secondly it is much, much smaller than an adults'.
May be absent in the fetus; if present it is unossified Quite a bit softer and smaller in the fetus. The kneecap develops throughout childhood and into mid-teens.
cartilaginous
The fetal skeleton is much softer, it has far more bones which fuse by adulthood. also the proporions are much more different, the skull of a fetus is much big in comparison to its body. obviously the fetal skeleton is much much smaller and is more fraile.as development of the facial area of a human develop, the head becomes much less round (so a fetal skeleton would have a rounder head). the face also becomes more defined and features more noticable. I hope this helps.
Why is a transplant consisting of fetal tissue less likely to provoke an immune rejection response than tissue from an adult?
The ossific centers appear in the intervals between the articular depressions for the coastal cartilages, in the following order: in the manubrium and first piece of the body, during the sixth month; in the second and third pieces of the body, during the seventh month of fetal life; in its fourth piece, during the first year after birth; and in the xiphoid process, between the fifth and eighteenth years. Its component parts are not fused in the fetus.
In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.
it is weaker
There are many characteristics found in a fetal pig. Fetal pigs generally have all of the characteristics of an adult pig.
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.

fetal alcohol effect is not as severe
hahaha:) lol
4 or more
the fetal bones are much more delicate than the adult
No. It is hyaline cartilage
