Explanation:
Detailed explanation-1: -There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult. The reason for the variability in the number of bones is because some humans may have a varying number of ribs, vertebrae, and digits.
Detailed explanation-2: -Human skeleton has 207 bones. There are 11 pairs of ribs in man. Sternum is present on ventral side of the body.
Detailed explanation-3: -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). Other bones in a baby are partly made of cartilage.
