the fetal bones are much more delicate than the adult
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
The fetal vertebrae are comparing with adult from the curvatures. Some of the curvatures are not seen until after birth.
because fetal bones fuse together
no!
it is weaker
The human stomach is bigger than the fetal pig's. This of course is if the human is an adult human.
In the fetal skeleton, the ossa coxae (hip bones) are not fully fused, and they consist of three separate bones: ilium, ischium, and pubis. In the adult skeleton, these three bones have fused together to form a single hip bone. Additionally, the acetabulum, the socket where the femur connects to the hip bone, is not fully developed in the fetal skeleton but is complete in the adult skeleton.
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.
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.
In a fetus it is in the liver and I think spleen and in an adult or any child it is in the bones if that answers your question.
Fetal pigs are not as developed as an adult.
