They fuse because of age.
You do not really 'lose' bones but some fuse together. Particularly the bones in the cranium.
because fetal bones fuse together
Yes, we are born with over 300 bones and some fuse together leaving 206 in adulthood. Examples are the scull, sacrum and coxyx.
they fuse together
Babies are born with around 270 bones, but as they grow, some bones fuse together. Examples of bones that babies have that adults do not include fontanelle bones in the skull, which eventually fuse to form the adult skull structure.
The three bones that fuse early in life are the sacrum, which is formed by the fusion of five sacral vertebrae, the ilium, and the ischium. Together, these bones form the pelvic girdle, which provides support and protection to the organs in the pelvic region.
because as you grow up bones fuse together and become stronger
206, although infants will have more - these extra bones will then fuse together as they grow.
They fuse together.
Adult bones fuse together as part of the natural aging process, known as skeletal maturation. This fusion occurs as the bone growth plates, also called epiphyseal plates, close and ossify, usually in the late teens to mid-20s. Once this fusion is complete, the bones stop growing in length and become a single, solid structure.
In childhood, several bones in the human body fuse together as part of the natural growth process. For example, the bones in the skull fuse to form the cranium, while the epiphyses (growth plates) in long bones fuse to the diaphysis (shaft). This fusion process helps to provide stability and structure to the growing body.
