ANATOMY

Detailed explanation-1: -A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij).

Detailed explanation-2: -This is because babies have more cartilage than bone. New born babies have around 305 bones. A baby’s skeleton is mostly made up of cartilage.As a person grows up, most of this cartilage turns into bone in a process called ossification.By adulthood, the skeleton has just 206 bones.

Detailed explanation-3: -Changing bone as babies grow As your baby grows into childhood, much of that cartilage will be replaced by actual bone. But something else happens, which explains why 300 bones at birth become 206 bones by adulthood. Many of your baby’s bones will fuse together, which means the actual number of bones will decrease.

Detailed explanation-4: -Hint: The human skeleton refers to the internal framework of the body. It consists of 270 to 300 bones at birth. But this total number of bones decreases to 206 bones by adulthood as some bones fuse together.

Detailed explanation-5: -The baby skeleton has more bones and cartilages. During development many of these cartilages become bones by the process called ossification and some bones fuse to form a bigger bone reducing the number of bones to 206.
