it is weaker
Cartilage
4 or more
hahaha:) lol
No. It is hyaline cartilage
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.
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.
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.
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
A shark's skeleton is made up of cartilage.
During fetal development, the skeleton undergoes significant changes, primarily transitioning from a cartilage-based framework to a bony structure. Initially, the fetal skeleton is composed mostly of hyaline cartilage, which serves as a model for bone formation. As development progresses, ossification begins, where bone tissue replaces cartilage, resulting in a more rigid and supportive structure. This transformation is crucial for the developing fetus, allowing for growth and preparation for birth.
