by the time , most people are 17 to 21 years old , their bones have formed to their full size .
Their bodies are not fully formed...
In fully formed, non-growing bones, cartilage is found on the ends of bones where they articulate with other bones.
No, bones do not undergo mitosis. Bone cells, such as osteoblasts and osteoclasts, are formed through a process called osteogenesis from stem cells. Once bones are fully formed, they do not undergo cell division like mitosis.
In my point of view it's because their bones aren't fully delvelpoed as we have.. so that's why and they are not formed..even know for a 16 year old person will still have some bones that aren't fully delepoed .. like mushed up bones still aiting to be develpped
All bones start as cartilage and over time they turn to bone.
There are two ways bones are formed, intramembranous ossification, and endochondral ossification. Intramembranous ossification is how the flat bones are formed, while the long bones are formed with endochondral ossification.
The pelvis is formed of 3 fused bones: the illium, ishium, and pubis. The sacrum is formed of 5 fused bones. And the coccyx is formed of 2-4 bones.
there are 29328 bones in your body.
People neither add nor lose bones, normally, in the course of their lives, although accidents can happen. However, the bones of a newborn baby are not fully formed, and have sections that are not fused together yet. If we count all the separate bone pieces as bones, a baby is born with over 300 bones, and a adult will normally have 206 bones.
No. Its called a skull.
Red bone marrow makes red blood cells and this is found in all infant and children's bones. In adults most of the red marrow has been replaced with yellow marrow which is fat tissue. Bones that are ossified have fully formed and are adult bones.
Not fully developed is partial formed.
