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.
Two characteristics of the fetal skeleton skull that differ from the adult skeleton are the presence of fontanelles (soft spots) in the fetal skull that allow for flexibility during childbirth, and the incomplete fusion of cranial bones in the fetus compared to the fully fused bones in adults.
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.
The skeleton is originally cartilaginous during fetal development. Over time, the cartilage is replaced by bone in a process called endochondral ossification, where bone tissue gradually forms and replaces the cartilage framework.
Fetal vertebrae are smaller in size and appear more cartilaginous compared to adult vertebrae. Fetal vertebrae also have different proportions and shapes which change as they mature into adult vertebrae, with the presence of ossification centers being a key difference.
Fetal tissue has lower levels of antigens, which are markers that the immune system recognizes as foreign. This makes fetal tissue less likely to provoke an immune response compared to adult tissue, which has a higher amount of antigens. Fetal tissue also has a higher ability to induce immune tolerance.
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
it is weaker
the fetal bones are much more delicate than the adult
The fetal vertebrae are comparing with adult from the curvatures. Some of the curvatures are not seen until after birth.

The human stomach is bigger than the fetal pig's. This of course is if the human is an adult human.
Cartilage
4 or more
hahaha:) lol
No. It is hyaline cartilage
Fetal pigs are not as developed as an adult.
no
