The bone of a fetus are composed mainly of cartilage.
Yes, it is true that in a developing fetus, the long bones are initially formed from hyaline cartilage. This cartilage serves as a scaffold that is gradually converted into bone through a process known as endochondral ossification.
At the time of birth a child has 300 bones but these bones fuse with each other as the child grows up and at adulthood the figure drops to 206.
No, the bones of the ribcage are not considered long bones. Long bones are typically found in the arms and legs, whereas the ribs are classified as flat bones.
Yes, the frontal and mandibular bones are paired in the fetus and fuse after birth. The frontal bone forms the forehead and part of the skull, while the mandibular bone forms the lower jaw. During fetal development, these bones start as separate structures and gradually fuse together after birth to form a single bone.
An embryo typically develops into a fetus around 8 weeks after fertilization. At this point, the major organs have begun to form and the fetus starts to resemble a human.
